Bump PKGREVISION.
Fix some pkglint while here.
|
|
The R package installs the file lib/R/etc/Makeconf, which is intended
to be used by R packages that themselves compile programs. This
feature is rarely used, but the math/R-nimble package is an example of
one that does. For this to work, the compiler flags embedded within
Makeconf must be compatible with the system compiler. At least on
MacOS, this is not the case by default, and so nimble compilations
fail. This substitutes ${COMPILER_RPATH_FLAG} into configure.ac, so
that it is used when creating Makeconf. Since neither R itself nor
most R packages compile other programs, Makeconf is generally not used
and this fix will have no impact.

CHANGES IN R 4.1.3:
NEW FEATURES:
* The default version of Bioconductor has been changed to 3.14.
(This is used by setRepositories and the menus in GUIs.)
UTILITIES:
* R CMD check --as-cran has a workaround for a bug in versions of
file up to at least 5.41 which mis-identify DBF files last
changed in 2022 as executables.
C-LEVEL FACILITIES:
* The legacy S-compatibility macros SINGLE_* in R_ext/Constants.h
(included by R.h) are deprecated and will be removed in R 4.2.0.
BUG FIXES:
* Initialization of self-starting nls() models with initialization
functions following the pre-R-4.1.0 API (without the ...
argument) works again for now, with a deprecation warning.
* Fixed quoting of ~autodetect~ in Java setting defaults to avoid
inadvertent user lookup due to leading ~, reported in PR#18231 by
Harold Gutch.
* substr(., start, stop) <- v now treats _negative_ stop values
correctly. Reported with a patch in PR#18228 by Brodie Gaslam.
* Subscripting an array x without dimnames by a
length(dim(x))-column character matrix gave "random" non-sense,
now an error; reported in PR#18244 by Mikael Jagan.
* ...names() now matches names(list(...)) closely, fixing PR#18247.
* all.equal(*, scale = s) now works as intended when length(s) > 1,
partly thanks to Michael Chirico's PR#18272.
* print(x) for long vectors x now also works for named atomic
vectors or lists and prints the correct number when reaching the
getOption("max.print") limit; partly thanks to a report and
proposal by Hugh Parsonage to the R-devel list.
* all.equal(<selfStart>, *) no longer signals a deprecation
warning.
* reformulate(*, response=r) gives a helpful error message now when
length(r) > 1, thanks to Bill Dunlap's PR#18281.
* Modifying globalCallingHandlers inside withCallingHandlers() now
works or fails correctly, thanks to Henrik Bengtsson's PR#18257.
* hist(<Date>, breaks = "days") and hist(<POSIXt>, breaks = "secs")
no longer fail for inputs of length 1.
* qbeta(.001, .9, .009) and similar cases now converge correctly
thanks to Ben Bolker's report in PR#17746.
* window(x, start, end) no longer wrongly signals "'start' cannot
be after 'end'", fixing PR#17527 and PR#18291.
* data() now checks that its (rarely used) list argument is a
character vector - a couple of packages passed other types and
gave incorrect results.
* which() now checks its arr.ind argument is TRUE rather coercing
to logical and taking the first element - which gave incorrect
results in package code.
* model.weights() and model.offset() more carefully extract their
model components, thanks to Ben Bolker and Tim Taylor's R-devel
post.
* list.files(recursive = TRUE) now shows all broken symlinks
(previously, some of them may have been omitted, PR#18296).

Add a comment to the Makefile to hopefully avoid macOS users constantly being
broken on every update.

CHANGES IN R 4.1.2:
C-LEVEL FACILITIES:
* The workaround in headers R.h and Rmath.h (using namespace std;)
for the Oracle Developer Studio compiler is no longer needed now
C++11 is required so has been removed. A couple more usages of
log() (which should have been std::log()) with an int argument
are reported on Solaris.
* The undocumented limit of 4095 bytes on messages from the
S-compatibility macros PROBLEM and MESSAGE is now documented and
longer messages will be silently truncated rather than
potentially causing segfaults.
* If the R_NO_SEGV_HANDLER environment variable is non-empty, the
signal handler for SEGV/ILL/BUS signals (which offers recovery
user interface) is not set. This allows more reliable debugging
of crashes that involve the console.
DEPRECATED AND DEFUNCT:
* The legacy S-compatibility macros PROBLEM, MESSAGE, ERROR, WARN,
WARNING, RECOVER, ... are deprecated and will be hidden in R
4.2.0. R's native interface of Rf_error and Rf_warning has long
been preferred.
BUG FIXES:
* .mapply(F, dots, .) no longer segfaults when dots is not a list
and uses match.fun(F) as always documented; reported by Andrew
Simmons in PR#18164.
* hist(<Date>, ...) and hist(<POSIXt>, ...) no longer pass
arguments for rect() (such as col and density) to axis().
(Thanks to Sebastian Meyer's PR#18171.)
* \Sexpr{ch} now preserves Encoding(ch). (Thanks to report and
patch by Jeroen Ooms in PR#18152.)
* Setting the RNG to "Marsaglia-Multicarry" e.g., by RNGkind(), now
warns in more places, thanks to Andr'e Gillibert's report and
patch in PR#18168.
* gray(numeric(), alpha=1/2) no longer segfaults, fixing PR#18183,
reported by Till Krenz.
* Fixed dnbinom(x, size=<very_small>, .., log=TRUE) regression,
reported by Martin Morgan.
* as.Date.POSIXlt(x) now keeps names(x), thanks to Davis Vaughan's
report and patch in PR#18188.
* model.response() now strips an "AsIs" class typically, thanks to
Duncan Murdoch's report and other discussants in PR#18190.
* try() is considerably faster in case of an error and long call,
as e.g., from some do.call(). Thanks to Alexander Kaever's
suggestion posted to R-devel.
* qqline(y = <object>) such as y=I(.), now works, see also
PR#18190.
* Non-integer mgp par() settings are now handled correctly in
axis() and mtext(), thanks to Mikael Jagan and Duncan Murdoch's
report and suggestion in PR#18194.
* formatC(x) returns length zero character() now, rather than ""
when x is of length zero, as documented, thanks to Davis
Vaughan's post to R-devel.
* removeSource(fn) now retains (other) attributes(fn).

CHANGES IN R 4.1.1:
NEW FEATURES:
* require(pkg, quietly = TRUE) is quieter and in particular does
not warn if the package is not found.
DEPRECATED AND DEFUNCT:
* Use of ftp:// URIs should be regarded as deprecated, with
on-going support confined to method = "libcurl" and not routinely
tested. (Nowadays no major browser supports them.)
* The non-default method = "internal" is deprecated for http:// and
ftp:// URIs for both download.file and url.
* On Windows, method = "wininet" is deprecated for http://,
https:// and ftp:// URIs for both download.file and url. (A
warning is only given for ftp://.)
For ftp:// URIs the default method is now "libcurl" if available
(which it is on CRAN builds).
method = "wininet" remains the default for http:// and https://
URIs but if libcurl is available, using method = "libcurl" is
preferred.
INSTALLATION:
* make check now works also without a LaTeX installation. (Thanks
to Sebastian Meyer's PR#18103.)
BUG FIXES:
* make check-devel works again in an R build configured with
--without-recommended-packages.
* qnbinom(p, size, mu) for large size/mu is correct now in a range
of cases (PR#18095); similarly for the (size, prob)
parametrization of the negative binomial. Also qpois() and
qbinom() are better and or faster for extreme cases. The
underlying C code has been modularized and is common to all four
cases of discrete distributions.
* gap.axis is now part of the axis() arguments which are passed
from bxp(), and hence boxplot(). (Thanks to Martin Smith's
report and suggestions in PR#18109.)
* .First and .Last can again be set from the site profile.
* seq.int(from, to, *) and seq.default(..) now work better in large
range cases where from-to is infinite where the two boundaries
are finite.
* all.equal(x,y) now returns TRUE correctly also when several
entries of abs(x) and abs(y) are close to .Machine$double.xmax,
the largest finite numeric.
* model.frame() now clears the object bit when removing the class
attribute of a value via na.action (PR#18100).
* charClass() now works with multi-character strings on Windows
(PR#18104, fixed by Bill Dunlap).
* encodeString() on Solaris now works again in Latin-1 encoding on
characters represented differently in UTF-8. Support for
surrogate pairs on Solaris has been improved.
* file.show() on Windows now works with non-ASCII path names
representable in the current native encoding (PR#18132).
* Embedded R on Windows can now find R home directory via the
registry even when installed only for the current user
(PR#18135).
* pretty(x) with finite x now returns finite values also in the
case where the extreme x values are close in size to the maximal
representable number .Machine$double.xmax.
Also, it's been tweaked for very small ranges and when a boundary
is close (or equal) to zero; e.g., pretty(c(0,1e-317)) no longer
has negative numbers, currently still warning about a very small
range, and pretty(2^-(1024 - 2^-1/(c(24,10)))) is more accurate.
* The error message for not finding vignette files when weaving has
correct file sizes now. (Thanks to Sebastian Meyer's PR#18154.)
* dnbinom(20, <large>, 1) now correctly gives 0, and similar cases
are more accurate with underflow precaution. (Reported by
Francisco Vera Alcivar in PR#18072.)

This used to not actaully honour our BLAS choice, the usage of
BLAS_LIBS was missing.

CHANGES IN R 4.1.0:
FUTURE DIRECTIONS:
* It is planned that the 4.1.x series will be the last to support
32-bit Windows, with production of binary packages for that
series continuing until early 2023.
SIGNIFICANT USER-VISIBLE CHANGES:
* Data set esoph in package datasets now provides the correct
numbers of controls; previously it had the numbers of cases added
to these. (Reported by Alexander Fowler in PR#17964.)
NEW FEATURES:
* www.omegahat.net is no longer one of the repositories known by
default to setRepositories(). (Nowadays it only provides source
packages and is often unavailable.)
* Function package_dependencies() (in package tools) can now use
different dependency types for direct and recursive dependencies.
* The checking of the size of tarball in R CMD check --as-cran
<pkg> may be tweaked via the new environment variable
_R_CHECK_CRAN_INCOMING_TARBALL_THRESHOLD_, as suggested in
PR#17777 by Jan Gorecki.
* Using c() to combine a factor with other factors now gives a
factor, an ordered factor when combining ordered factors with
identical levels.
* apply() gains a simplify argument to allow disabling of
simplification of results.
* The format() method for class "ftable" gets a new option justify.
(Suggested by Thomas Soeiro.)
* New ...names() utility. (Proposed by Neal Fultz in PR#17705.)
* type.convert() now warns when its as.is argument is not
specified, as the help file always said it _should_. In that
case, the default is changed to TRUE in line with its change in
read.table() (related to stringsAsFactor) in R 4.0.0.
* When printing list arrays, classed objects are now shown _via_
their format() value if this is a short enough character string,
or by giving the first elements of their class vector and their
length.
* capabilities() gets new entry "Rprof" which is TRUE when R has
been configured with the equivalent of --enable-R-profiling (as
it is by default). (Related to Michael Orlitzky's report
PR#17836.)
* str(xS4) now also shows extraneous attributes of an S4 object
xS4.
* Rudimentary support for vi-style tags in rtags() and R CMD rtags
has been added. (Based on a patch from Neal Fultz in PR#17214.)
* checkRdContents() is now exported from tools; it and also
checkDocFiles() have a new option chkInternal allowing to check
Rd files marked with keyword "internal" as well. The latter can
be activated for R CMD check via environment variable
_R_CHECK_RD_INTERNAL_TOO_.
* New functions numToBits() and numToInts() extend the raw
conversion utilities to (double precision) numeric.
* Functions URLencode() and URLdecode() in package utils now work
on vectors of URIs. (Based on patch from Bob Rudis submitted
with PR#17873.)
* path.expand() can expand ~user on most Unix-alikes even when
readline is not in use. It tries harder to expand ~, for example
should environment variable HOME be unset.
* For HTML help (both dynamic and static), Rd file links to help
pages in external packages are now treated as references to
topics rather than file names, and fall back to a file link only
if the topic is not found in the target package. The earlier rule
which prioritized file names over topics can be restored by
setting the environment variable _R_HELP_LINKS_TO_TOPICS_ to a
false value.
* c() now removes NULL arguments before dispatching to methods,
thus simplifying the implementation of c() methods, _but_ for
back compatibility keeps NULL when it is the first argument.
(From a report and patch proposal by Lionel Henry in PR#17900.)
* Vectorize()'s result function's environment no longer keeps
unneeded objects.
* Function ...elt() now propagates visibility consistently with
..n. (Thanks to Lionel Henry's PR#17905.)
* capture.output() no longer uses non-standard evaluation to
evaluate its arguments. This makes evaluation of functions like
parent.frame() more consistent. (Thanks to Lionel Henry's
PR#17907.)
* packBits(bits, type="double") now works as inverse of
numToBits(). (Thanks to Bill Dunlap's proposal in PR#17914.)
* curlGetHeaders() has two new arguments, timeout to specify the
timeout for that call (overriding getOption("timeout")) and TLS
to specify the minimum TLS protocol version to be used for
https:// URIs (_inter alia_ providing a means to check for sites
using deprecated TLS versions 1.0 and 1.1).
* For nls(), an optional constant scaleOffset may be added to the
denominator of the relative offset convergence test for cases
where the fit of a model is expected to be exact, thanks to a
proposal by John Nash. nls(*, trace=TRUE) now also shows the
convergence criterion.
* Numeric differentiation _via_ numericDeriv() gets new optional
arguments eps and central, the latter for taking central divided
differences. The latter can be activated for nls() via
nls.control(nDcentral = TRUE).
* nls() now passes the trace and control arguments to getInitial(),
notably for all self-starting models, so these can also be fit in
zero-noise situations via a scaleOffset. For this reason, the
initial function of a selfStart model must now have ... in its
argument list.
* bquote(splice = TRUE) can now splice expression vectors with
attributes: this makes it possible to splice the result of
parse(keep.source = TRUE). (Report and patch provided by Lionel
Henry in PR#17869.)
* textConnection() gets an optional name argument.
* get(), exists(), and get0() now signal an error if the first
argument has length greater than 1. Previously additional
elements were silently ignored. (Suggested by Antoine Fabri on
R-devel.)
* R now provides a shorthand notation for creating functions, e.g.
\(x) x + 1 is parsed as function(x) x + 1.
* R now provides a simple native forward pipe syntax |>. The
simple form of the forward pipe inserts the left-hand side as the
first argument in the right-hand side call. The pipe
implementation as a syntax transformation was motivated by
suggestions from Jim Hester and Lionel Henry.
* all.equal(f, g) for functions now by default also compares their
environment(.)s, notably via new all.equal method for class
function. Comparison of nls() fits, e.g., may now need
all.equal(m1, m2, check.environment = FALSE).
* .libPaths() gets a new option include.site, allowing to _not_
include the site library. (Thanks to Dario Strbenac's suggestion
and Gabe Becker's PR#18016.)
* Lithuanian translations are now available. (Thanks to Rimantas
Zakauskas.)
* names() now works for DOTSXP objects. On the other hand, in
R-lang, the R language manual, we now warn against relying on the
structure or even existence of such dot-dot-dot objects.
* all.equal() no longer gives an error on DOTSXP objects.
* capabilities("cairo") now applies only to the file-based devices
as it is now possible (if very unusual) to build R with Cairo
support for those but not for X11().
* There is optional support for tracing the progress of
loadNamespace() - see its help.
* (Not Windows.) l10n_info() reports an additional element, the
name of the encoding as reported by the OS (which may differ from
the encoding part (if any) of the result from
Sys.getlocale("LC_CTYPE").
* New function gregexec() which generalizes regexec() to find _all_
disjoint matches and well as all substrings corresponding to
parenthesized subexpressions of the given regular expression.
(Contributed by Brodie Gaslam.)
* New function charClass() in package utils to query the
wide-character classification functions in use (such as
iswprint).
* The names of quantile()'s result no longer depend on the global
getOption("digits"), but quantile() gets a new optional argument
digits = 7 instead.
* grep(), sub(), regexp and variants work considerably faster for
long factors with few levels. (Thanks to Michael Chirico's
PR#18063.)
* Provide grouping of x11() graphics windows within a window
manager such as Gnome or Unity; thanks to a patch by Ivan Krylov
posted to R-devel.
* The split() method for class data.frame now allows the f argument
to be specified as a formula.
* sprintf now warns on arguments unused by the format string.
* New palettes "Rocket" and "Mako" for hcl.colors() (approximating
palettes of the same name from the 'viridisLite' package).
Contributed by Achim Zeileis.
* The base environment and its namespace are now locked (so one can
no longer add bindings to these or remove from these).
* Rterm handling of multi-byte characters has been improved,
allowing use of such characters when supported by the current
locale.
* Rterm now accepts ALT+ +xxxxxxxx sequences to enter Unicode
characters as hex digits.
* Environment variable LC_ALL on Windows now takes precedence over
LC_CTYPE and variables for other supported categories, matching
the POSIX behaviour.
* duplicated() and anyDuplicated() are now optimized for integer
and real vectors that are known to be sorted via the ALTREP
framework. Contributed by Gabriel Becker via PR#17993.
GRAPHICS:
* The graphics engine version, R_GE_version, has been bumped to 14
and so packages that provide graphics devices should be
reinstalled.
* Graphics devices should now specify deviceVersion to indicate
what version of the graphics engine they support.
* Graphics devices can now specify deviceClip. If TRUE, the
graphics engine will never perform any clipping of output itself.
The clipping that the graphics engine does perform (for both
canClip = TRUE and canClip = FALSE) has been improved to avoid
producing unnecessary artifacts in clipped output.
* The grid package now allows gpar(fill) to be a linearGradient(),
a radialGradient(), or a pattern(). The viewport(clip) can now
also be a grob, which defines a clipping path, and there is a new
viewport(mask) that can also be a grob, which defines a mask.
These new features are only supported so far on the Cairo-based
graphics devices and on the pdf() device.
* (Not Windows.) A warning is given when a Cairo-based type is
specified for a png(), jpeg(), tiff() or bmp() device but Cairo
is unsupported (so type = "Xlib" is tried instead).
* grSoftVersion() now reports the versions of FreeType and
FontConfig if they are used directly (not _via_ Pango), as is
most commonly done on macOS.
C-LEVEL FACILITIES:
* The _standalone_ libRmath math library and R's C API now provide
log1pexp() again as documented, and gain log1mexp().
INSTALLATION on a UNIX-ALIKE:
* configure checks for a program pkgconf if program pkg-config is
not found. These are now only looked for on the path (like
almost all other programs) so if needed specify a full path to
the command in PKG_CONFIG, for example in file config.site.
* C99 function iswblank is required - it was last seen missing ca
2003 so the workaround has been removed.
* There are new configure options --with-internal-iswxxxxx,
--with-internal-towlower and --with-internal-wcwidth which allows
the system functions for wide-character classification,
case-switching and width (wcwidth and wcswidth) to be replaced by
internal ones. The first has long been used on macOS, AIX (and
Windows) but this enables it to be unselected there and selected
for other platforms (it is the new default on Solaris). The
second is new in this version of R and is selected by default on
macOS and Solaris. The third has long been the default and
remains so as it contains customizations for East Asian
languages.
System versions of these functions are often minimally
implemented (sometimes only for ASCII characters) and may not
cover the full range of Unicode points: for example Solaris (and
Windows) only cover the Basic Multilingual Plane.
* Cairo installations without X11 are more likely to be detected by
configure, when the file-based Cairo graphics devices will be
available but not X11(type = "cairo").
* There is a new configure option --with-static-cairo which is the
default on macOS. This should be used when only static cairo
(and where relevant, Pango) libraries are available.
* Cairo-based graphics devices on platforms without Pango but with
FreeType/FontConfig will make use of the latter for font
selection.
LINK-TIME OPTIMIZATION on a UNIX-ALIKE:
* Configuring with flag --enable-lto=R now also uses LTO when
installing the recommended packages.
* R CMD INSTALL and R CMD SHLIB have a new flag --use-LTO to use
LTO when compiling code, for use with R configured with
--enable-lto=R. For R configured with --enable-lto, they have
the new flag --no-use-LTO.
Packages can opt in or out of LTO compilation _via_ a UseLTO
field in the DESCRIPTION file. (As usual this can be overridden
by the command-line flags.)
BUILDING R on Windows:
* for GCC >= 8, FC_LEN_T is defined in config.h and hence character
lengths are passed from C to Fortran in _inter alia_ BLAS and
LAPACK calls.
* There is a new text file src/gnuwin32/README.compilation, which
outlines how C/Fortran code compilation is organized and
documents new features:
* R can be built with Link-Time Optimization with a suitable
compiler - doing so with GCC 9.2 showed several
inconsistencies which have been corrected.
* There is support for cross-compiling the C and Fortran code
in R and standard packages on suitable (Linux) platforms.
This is mainly intended to allow developers to test later
versions of compilers - for example using GCC 9.2 or 10.x has
detected issues that GCC 8.3 in Rtools40 does not.
* There is experimental support for cross-building R packages
with C, C++ and/or Fortran code.
* The R installer can now be optionally built to support a single
architecture (only 64-bit or only 32-bit).
PACKAGE INSTALLATION:
* The default C++ standard has been changed to C++14 where
available (which it is on all currently checked platforms): if
not (as before) C++11 is used if available otherwise C++ is not
supported.
Packages which specify C++11 will still be installed using C++11.
C++14 compilers may give deprecation warnings, most often for
std::random_shuffle (deprecated in C++14 and removed in C++17).
Either specify C++11 (see 'Writing R Extensions') or modernize
the code and if needed specify C++14. The latter has been
supported since R 3.4.0 so the package's DESCRIPTION would need
to include something like
Depends: R (>= 3.4)
PACKAGE INSTALLATION on Windows:
* R CMD INSTALL and R CMD SHLIB make use of their flag --use-LTO
when the LTO_OPT make macro is set in file etc/${R_ARCH}/Makeconf
or in a personal/site Makevars file. (For details see 'Writing R
Extensions' SS4.5.)
This provides a valuable check on code consistency. It does work
with GCC 8.3 as in Rtools40, but that does not detect everything
the CRAN checks with current GCC do.
PACKAGE INSTALLATION on macOS:
* The default personal library directory on builds with
--enable-aqua (including CRAN builds) now differs by CPU type,
one of
~/Library/R/x86_64/x.y/library
~/Library/R/arm64/x.y/library
This uses the CPU type R (and hence the packages) were built for,
so when a x86_64 build of R is run under Rosetta emulation on an
arm64 Mac, the first is used.
UTILITIES:
* R CMD check can now scan package functions for bogus return
statements, which were possibly intended as return() calls (wish
of PR#17180, patch by Sebastian Meyer). This check can be
activated via the new environment variable
_R_CHECK_BOGUS_RETURN_, true for --as-cran.
* R CMD build omits tarballs and binaries of previous builds from
the top-level package directory. (PR#17828, patch by Sebastian
Meyer.)
* R CMD check now runs sanity checks on the use of LazyData, for
example that a data directory is present and that
LazyDataCompression is not specified without LazyData and has a
documented value. For packages with large LazyData databases
without specifying LazyDataCompression, there is a reference to
the code given in 'Writing R Extensions' SS1.1.6 to test the
choice of compression (as in all the CRAN packages tested a
non-default method was preferred).
* R CMD build removes LazyData and LazyDataCompression fields from
the DESCRIPTION file of packages without a data directory.
ENCODING-RELATED CHANGES:
* The parser now treats \Unnnnnnnn escapes larger than the upper
limit for Unicode points (\U10FFFF) as an error as they cannot be
represented by valid UTF-8.
Where such escapes are used for outputting non-printable
(including unassigned) characters, 6 hex digits are used (rather
than 8 with leading zeros). For clarity, braces are used, for
example \U{0effff}.
* The parser now looks for non-ASCII spaces on Solaris (as
previously on most other OSes).
* There are warnings (including from the parser) on the use of
unpaired surrogate Unicode points such as \uD834. (These cannot
be converted to valid UTF-8.)
* Functions nchar(), tolower(), toupper() and chartr() and those
using regular expressions have more support for inputs with a
marked Latin-1 encoding.
* The character-classification functions used (by default) to
replace the system iswxxxxx functions on Windows, macOS and AIX
have been updated to Unicode 13.0.0.
The character-width tables have been updated to include new
assignments in Unicode 13.0.0.
* The code for evaluating default (extended) regular expressions
now uses the same character-classification functions as the rest
of R (previously they differed on Windows, macOS and AIX).
* There is a build-time option to replace the system's
wide-character wctrans C function by tables shipped with R: use
configure option --with-internal-towlower or (on Windows)
-DUSE_RI18N_CASE in CFLAGS when building R. This may be needed
to allow tolower() and toupper() to work with Unicode characters
beyond the Basic Multilingual Plane where not supported by system
functions (e.g. on Solaris where it is the new default).
* R is more careful when truncating UTF-8 and other multi-byte
strings that are too long to be printed, passed to the system or
libraries or placed into an internal buffer. Truncation will no
longer produce incomplete multibyte characters.
DEPRECATED AND DEFUNCT:
* Function plclust() from the package stats and
package.dependencies(), pkgDepends(), getDepList(),
installFoundDepends(), and vignetteDepends() from package tools
are defunct.
* Defunct functions checkNEWS() and readNEWS() from package tools
and CRAN.packages() from utils have been removed.
* R CMD config CXXCPP is defunct (it was deprecated in R 3.6.2).
* parallel::detectCores() drops support for Irix (retired in 2013).
* The LINPACK argument to chol.default(), chol2inv(),
solve.default() and svd() has been defunct since R 3.1.0. It was
silently ignored up to R 4.0.3 but now gives an error.
* Subsetting/indexing, such as ddd[*] or ddd$x on a DOTSXP
(dot-dot-dot) object ddd has been disabled; it worked by accident
only and was undocumented.
BUG FIXES:
* Many more C-level allocations (mainly by malloc and strdup) are
checked for success with suitable alternative actions.
* Bug fix for replayPlot(); this was turning off graphics engine
display list recording if a recorded plot was replayed in the
same session. The impact of the bug became visible if resize the
device after replay OR if attempted another savePlot() after
replay (empty display list means empty screen on resize or empty
saved plot).
* R CMD check etc now warn when a package exports non-existing S4
classes or methods, also in case of no "methods" presence.
(Reported by Alex Bertram; reproducible example and patch by
Sebastian Meyer in PR#16662.)
* boxplot() now also accepts calls for labels such as ylab, the
same as plot(). (Reported by Marius Hofert.)
* The help page for xtabs() now correctly states that addNA is
setting na.action = na.pass among others. (Reported as PR#17770
by Thomas Soeiro.)
* The R CMD check <pkg> gives a longer and more comprehensible
message when DESCRIPTION misses dependencies, e.g., in Imports:.
(Thanks to the contributors of PR#17179.)
* update.default() now calls the generic update() on the formula to
work correctly for models with extended formulas. (As reported
and suggested by Neal Fultz in PR#17865.)
* The horizontal position of leaves in a dendrogram is now correct
also with center = FALSE. (PR#14938, patch from Sebastian
Meyer.)
* all.equal.POSIXt() no longer warns about and subsequently ignores
inconsistent "tzone" attributes, but describes the difference in
its return value (PR#17277). This check can be disabled _via_
the new argument check.tzone = FALSE as suggested by Sebastian
Meyer.
* as.POSIXct() now populates the "tzone" attribute from its tz
argument when x is a logical vector consisting entirely of NA
values.
* x[[2^31]] <- v now works. (Thanks to the report and patch by
Suharto Anggono in PR#17330.)
* In log-scale graphics, axis() ticks and label positions are now
computed more carefully and symmetrically in their range,
typically providing _more_ ticks, fulfilling wishes in PR#17936.
The change really corresponds to an improved axisTicks() (package
grDevices), potentially influencing grid and lattice, for
example.
* qnorm(<very large negative>, log.p=TRUE) is now correct to at
least five digits where it was catastrophically wrong,
previously.
* sum(df) and similar "Summary"- and "Math"-group member functions
now work for data frames df with logical columns, notably also of
zero rows. (Reported to R-devel by Martin "b706".)
* unsplit() had trouble with tibbles due to unsound use of rep(NA,
len)-indexing, which should use NA_integer_ (Reported to R-devel
by Mario Annau.)
* pnorm(x, log.p = TRUE) underflows to -Inf slightly later.
* show(<hidden S4 generic>) prints better and without quotes for
non-hidden S4 generics.
* read.table() and relatives treated an "NA" column name as missing
when check.names = FALSE PR#18007.
* Parsing strings containing UTF-16 surrogate pairs such as
"\uD834\uDD1E" works better on some (uncommon) platforms.
sprintf("%X", utf8ToInt("\uD834\uDD1E")) should now give "1D11E"
on all platforms.
* identical(x,y) is no longer true for differing DOTSXP objects,
fixing PR#18032.
* str() now works correctly for DOTSXP and related exotics, even
when these are doomed.
Additionally, it no longer fails for lists with a class and
"irregular" method definitions such that e.g. lapply(*) will
necessarily fail, as currently for different igraph objects.
* Too long lines in environment files (e.g. Renviron) no longer
crash R. This limit has been increased to 100,000 bytes.
(PR#18001.)
* There is a further workaround for FreeType giving incorrect
italic font faces with cairo-based graphics devices on macOS.
* add_datalist(*, force = TRUE) (from package tools) now actually
updates an existing data/datalist file for new content. (Thanks
to a report and patch by Sebastian Meyer in PR#18048.)
* cut.Date() and cut.POSIXt() could produce an empty last interval
for breaks = "months" or breaks = "years". (Reported as PR#18053
by Christopher Carbone.)
* Detection of the encoding of 'regular' macOS locales such as
en_US (which is UTF-8) had been broken by a macOS change:
fortunately these are now rarely used with en_US.UTF-8 being
preferred.
* sub() and gsub(pattern, repl, x, *) now keep attributes of x such
as names() also when pattern is NA (PR#18079).
* Time differences ("difftime" objects) get a replacement and a
rep() method to keep "units" consistent. (Thanks to a report and
patch by Nicolas Bennett in PR#18066.)
* The \RdOpts macro, setting defaults for \Sexpr options in an Rd
file, had been ineffective since R 2.12.0: it now works again.
(Thanks to a report and patch by Sebastian Meyer in PR#18073.)
* mclapply and pvec no longer accidentally terminate parallel
processes started before by mcparallel or related calls in
package parallel (PR#18078).
* grep and other functions for evaluating (extended) regular
expressions handle in Unicode also strings not explicitly flagged
UTF-8, but flagged native when running in UTF-8 locale.
* Fixed a crash in fifo implementation on Windows (PR#18031).
* Binary mode in fifo on Windows is now properly detected from
argument open (PR#15600, PR#18031).

Install the new interchangeable BLAS system created by Thomas Orgis,
currently supporting Netlib BLAS/LAPACK, OpenBLAS, cblas, lapacke, and
Apple's Accelerate.framework. This system allows the user to select any
BLAS implementation without modifying packages or using package options, by
setting PKGSRC_BLAS_TYPES in mk.conf. See mk/blas.buildlink3.mk for details.
This commit should not alter behavior of existing packages as the system
defaults to Netlib BLAS/LAPACK, which until now has been the only supported
implementation.
Details:
Add new mk/blas.buildlink3.mk for inclusion in dependent packages
Install compatible Netlib math/blas and math/lapack packages
Update math/blas and math/lapack MAINTAINER approved by adam@
OpenBLAS, cblas, and lapacke will follow in separate commits

CHANGES IN R 4.0.3:
NEW FEATURES:
* On platforms using configure option --with-internal-tzcode,
additional values "internal" and (on macOS only) "macOS" are
accepted for the environment variable TZDIR. (See ?TZDIR.)
On macOS, "macOS" is used by default if the system timezone
database is a newer version than that in the R installation.
* When install.packages(type = "source") fails to find a package in
a repository it mentions package versions which are excluded by
their R version requirement and links to hints on why a package
might not be found.
* The default value for options("timeout") can be set from
enviromnent variable R_DEFAULT_INTERNET_TIMEOUT, still defaulting
to 60 (seconds) if that is not set or invalid.
This may be needed when child R processes are doing downloads,
for example during the installation of source packages which
download jars or other forms of data.
LINK-TIME OPTIMIZATION on a UNIX-ALIKE:
* There is now support for parallelized Link-Time Optimization
(LTO) with GCC and for 'thin' LTO with clang _via_ setting the
LTO macro.
* There is support for setting a different LTO flag for the Fortran
compiler, including to empty when mixing clang and gfortran (as
on macOS). See file config.site.
* There is a new LTO_LD macro to set linker options for LTO
compilation, for example to select an alternative linker or to
parallelize thin LTO.
DEPRECATED AND DEFUNCT:
* The LINPACK argument to chol.default(), chol2inv(),
solve.default() and svd() has been defunct since R 3.1.0. Using
it now gives a warning which will become an error in R 4.1.0.
BUG FIXES:
* The code mitigating stack overflow with PCRE regexps on very long
strings is enabled for PCRE2 < 10.30 also when JIT is enabled,
since stack overflows have been seen in that case.
* Fix to correctly show the group labels in dotchart() (which where
lost in the ylab improvement for R 4.0.0).
* addmargins(*, ..) now also works when fn() is a local function,
thanks to bug report and patch PR#17124 from Alex Bertram.
* rank(x) and hence sort(x) now work when x is an object (as per
is.object(x)) of type "raw" _and_ provides a valid `[` method,
e.g., for gmp::as.bigz(.) numbers.
* chisq.test(*, simulate.p.value=TRUE) and r2dtable() now work
correctly for large table entries (in the millions). Reported by
Sebastian Meyer and investigated by more helpers in PR#16184.
* Low-level socket read/write operations have been fixed to
correctly signal communication errors. Previously, such errors
could lead to a segfault due to invalid memory access. Reported
and debugged by Dmitriy Selivanov in PR#17850.
* quantile(x, pr) works more consistently for pr values slightly
outside [0,1], thanks to Suharto Anggono's PR#17891.
Further, quantile(x, prN, names=FALSE) now works even when prN
contains NAs, thanks to Anggono's PR#17892. Ditto for ordered
factors or Date objects when type = 1 or 3, thanks to PR#17899.
* Libcurl-based internet access, including curlGetHeaders(), was
not respecting the "timeout" option. If this causes
unanticipated timeouts, consider increasing the default by
setting R_DEFAULT_INTERNET_TIMEOUT.
* as.Date(<char>) now also works with an initial "", thanks to
Michael Chirico's PR#17909.
* isS3stdGeneric(f) now detects an S3 generic also when it it is
trace()d, thanks to Gabe Becker's PR#17917.
* R_allocLD() has been fixed to return memory aligned for long
double type PR#16534.
* fisher.test() no longer segfaults when called again after its
internal stack has been exceeded PR#17904.
* Accessing a long vector represented by a compact integer sequence
no longer segfaults (reported and debugged by Hugh Parsonage).
* duplicated() now works also for strings with multiple encodings
inside a single vector PR#17809.
* phyper(11, 15, 0, 12, log.p=TRUE) no longer gives NaN; reported
as PR#17271 by Alexey Stukalov.
* Fix incorrect calculation in logLik.nls() PR#16100, patch from
Sebastian Meyer.
* A very old bug could cause a segfault in model.matrix() when
terms involved logical variables. Part of PR#17879.
* model.frame.default() allowed data = 1, leading to involuntary
variable capture (rest of PR#17879).
* tar() no longer skips non-directory files, thanks to a patch by
Sebastian Meyer, fixing the remaining part of PR#16716.

CHANGES IN R 4.0.0:
SIGNIFICANT USER-VISIBLE CHANGES:
* Packages need to be (re-)installed under this version (4.0.0) of
R.
* matrix objects now also inherit from class "array", so e.g.,
class(diag(1)) is c("matrix", "array"). This invalidates code
incorrectly assuming that class(matrix_obj)) has length one.
S3 methods for class "array" are now dispatched for matrix
objects.
* There is a new syntax for specifying _raw_ character constants
similar to the one used in C++: r"(...)" with ... any character
sequence not containing the sequence )". This makes it easier to
write strings that contain backslashes or both single and double
quotes. For more details see ?Quotes.
* R now uses a stringsAsFactors = FALSE default, and hence by
default no longer converts strings to factors in calls to
data.frame() and read.table().
A large number of packages relied on the previous behaviour and
so have needed/will need updating.
* The plot() S3 generic function is now in package base rather than
package graphics, as it is reasonable to have methods that do not
use the graphics package. The generic is currently re-exported
from the graphics namespace to allow packages importing it from
there to continue working, but this may change in future.
Packages which define S4 generics for plot() should be
re-installed and package code using such generics from other
packages needs to ensure that they are imported rather than rely
on their being looked for on the search path (as in a namespace,
the base namespace has precedence over the search path).
See ${PREFIX}/lib/R/doc/NEWS for full changes.

CHANGES IN R 3.6.1:
INSTALLATION on a UNIX-ALIKE:
* The default detection of the shell variable libNN is overridden
for derivatives of Debian Linux, some of which have started to
have a /usr/lib64 directory. (E.g. Ubuntu 19.04.) As before, it
can be specified in config.site.
UTILITIES:
* R CMD config knows the values of AR and RANLIB, often set for LTO
builds.
DEPRECATED AND DEFUNCT:
* The use of a character vector with .Fortran() is formally
deprecated and gives a non-portability warning. (It has long
been strongly discouraged in 'Writing R Extensions'.)
BUG FIXES:
* On Windows, GUI package installation via menuInstallPkgs() works
again, thanks to Len Weil's and Duncan Murdoch's PR#17556.
* R CMD check on data() fixing PR#17558 thanks to Duncan Murdoch.
* quasi(*, variance = list(..)) now works more efficiently, and
should work in all cases fixing PR#17560. Further, quasi(var =
mu(1-mu)) and quasi(var = "mu ^ 3") now work, and quasi(variance
= "log(mu)") now gives a correct error message.
* Creation of lazy loading database during package installation is
again robust to Rprofile changing the current working directory
(PR#17559).
* boxplot(y ~ f, horizontal=TRUE) now produces correct x- and
y-labels.
* rbind.data.frame() allows to keep <NA> levels from factor columns
(PR#17562) via new option factor.exclude.
Additionally, it works in one more case with matrix-columns which
had been reported on 2017-01-16 by Krzysztof Banas.
* Correct messaging in C++ pragma checks in tools code for R CMD
check, fixing PR#17566 thanks to Xavier Robin.
* print()ing and auto-printing no longer differs for functions with
a user defined print.function, thanks to Bill Dunlap's report.
* On Windows, writeClipboard(.., format = <n>) now does correctly
pass format to the underlying C code, thanks to a bug report
(with patch) by Jenny Bryan.
* as.data.frame() treats 1D arrays the same as vectors, PR#17570.
* Improvements in smoothEnds(x, *) working with NAs (towards
runmed() working in that case, in the next version of R).
* vcov(glm(<quasi>), dispersion = *) works correctly again, fixing
PR#17571 thanks to Pavel Krivitsky.
* R CMD INSTALL of binary packages on Windows now works also with
per-directory locking.
* R CMD INSTALL and install.packages() on Windows are now more
robust against a locked file in an earlier installation of the
package to be installed. The default value of option
install.lock on Windows has been changed to TRUE.
* On Unix alikes (when readline is active), only expand tilde (~)
file names starting with a tilde, instead of almost all tildes.
* In R documentation (*.Rd) files, \item [..] is no longer treated
specially when rendered in LaTeX and hence pdf, but rather shows
the brackets in all cases.

The category 'R' is used to denote R packages, just as 'perl5' and 'python'
are used in other cases. To ensure consistency, add that to CATEGORIES in
Makefile.extension rather than in each individual R package. This was
discussed in http://mail-index.netbsd.org/tech-pkg/2019/08/02/msg021711.html.

Upstream changes:
CHANGES IN R 3.6.0:
SIGNIFICANT USER-VISIBLE CHANGES:
* Serialization format version 3 becomes the default for
serialization and saving of the workspace (save(), serialize(),
saveRDS(), compiler::cmpfile()). Serialized data in format 3
cannot be read by versions of R prior to version 3.5.0.
Serialization format version 2 is still supported and can be
selected by version = 2 in the save/serialization functions. The
default can be changed back for the whole R session by setting
environment variables R_DEFAULT_SAVE_VERSION and
R_DEFAULT_SERIALIZE_VERSION to 2. For maximal
back-compatibility, files vignette.rds and partial.rdb generated
by R CMD build are in serialization format version 2, and resave
by default produces files in serialization format version 2
(unless the original is already in format version 3).
* The default method for generating from a discrete uniform
distribution (used in sample(), for instance) has been changed.
This addresses the fact, pointed out by Ottoboni and Stark, that
the previous method made sample() noticeably non-uniform on large
populations. See PR#17494 for a discussion. The previous method
can be requested using RNGkind() or RNGversion() if necessary for
reproduction of old results. Thanks to Duncan Murdoch for
contributing the patch and Gabe Becker for further assistance.
The output of RNGkind() has been changed to also return the
'kind' used by sample().
NEW FEATURES:
* Sys.setFileTime() has been vectorized so arguments path and time
of length greater than one are now supported.
* axis() gets new option gap.axis = NA for specifying a
multiplication factor for the minimal "gap" (distance) between
axis labels drawn. Its default is 1 for labels _parallel_ to the
axis, and 0.25 for perpendicular ones.
Perpendicular labels no longer overlap, fixing bug PR#17384.
* The default method of plot() gains new arguments xgap.axis = NA
and ygap.axis = NA to be passed to the x- and y- axis(..,
gap.axis=*) calls.
* removeSource() now works not only for functions but also for some
language objects.
* as.call(), rep.int(), rep_len() and nchar() dispatch internally.
* is(object, class2) looks for class2 in the calling namespace
after looking in the namespace of class(object).
* extendrange(.., f) with a length-2 f now extends separately to
the left and the right.
* lengths() dispatches internally to S4 methods.
* download.file() on Windows now uses URLdecode() to determine the
file extension, and uses binary transfer (mode = "wb") also for
file extension .rds.
The help page for download.file() now contains the same
information on all platforms.
* Setting C locale for collation _via_ environment variables LC_ALL
and LC_COLLATE and _via_ a call to Sys.setlocale() now takes
precedence over environment variable R_ICU_LOCALE.
* There is a new function, nullfile(), to give the file name of the
null system device (e.g., /dev/null) on the current platform.
* There are two new options, keep.parse.data and
keep.parse.data.pkgs, which control whether parse data are
included into sources when keep.source or keep.source.pkgs is
TRUE. By default, keep.parse.data.pkgs is now FALSE, which
changes previous behavior and significantly reduces space and
time overhead when sources are kept when installing packages.
* In rapply(x, ..), x can also be "list-like" and of length >=
2^{31}.
* trimws() gets new optional whitespace argument, allowing more
extensive definitions of "space", such as including Unicode
spaces (as wished in PR#17431).
* weighted.mean() no longer coerces the weights to a double/numeric
vector, since sum() now handles integer overflow. This makes
weighted.mean() more polymorphic and endomorphic, but be aware
that the results are no longer guaranteed to be a vector of type
double.
* When loading namespaces, S3 method registrations which overwrite
previous registrations are now noted by default (using
packageStartupMessage()).
* compiler::cmpfile() gains a version argument, for use when the
output file should be saved in serialization format 2.
* The axis labeling in the default method of pairs() may now be
toggled by new options horOdd and verOdd.
* (Not Windows nor macOS.) Package tcltk now supports an
environment variable R_DONT_USE_TK which if set disables Tk
initialization. This is intended for use to circumvent errors in
loading the package, e.g. with recent Linux running under an
address sanitizer.
* The numeric method of all.equal() gets optional arguments countEQ
and formatFUN. If countEQ is true, the mean error is more
sensible when many entries are *eq*ual.
* outer(x,y, FUN = "*") is more efficient using tcrossprod(u,v)
instead of u %*% t(v).
* vcov(<mlm>) is more efficient via new optional arguments in
summary.mlm().
* The default method of summary() gets an option to choose the
_kind_ of quantile()s to use; wish of PR#17438.
* Fitting multiple linear models _via_ lm() does work with _matrix_
offsets, as suggested in PR#17407.
* The new functions mem.maxVSize() and mem.maxMSize() allow the
maximal size of the vector heap and the maximal number of nodes
allowed in the current R process to be queried and set.
* news() gains support for NEWS.md files.
* An effort has been started to have our reference manuals, i.e.,
all help pages. show platform-independent information (rather
than Windows or Unix-alike specifics visible only on that
platform). Consequently, the Windows version of X11() / x11()
got identical formal arguments to the Unix one.
* sessionInfo()$running has been factored out in a new variable
osVersion.
* slice.index() now also works for multi-dimensional margins.
* untar() used with an external tar command assumes this supports
decompression including xz and automagically detecting the
compression type. This has been true of all mainstream
implementations since 2009 (for GNU tar, since version 1.22):
older implementations are still supported _via_ the new argument
support_old_tars whose default is controlled by environment
variable R_SUPPORT_OLD_TARS. (It looks like NetBSD and OpenBSD
have 'older' tar commands for this purpose.)
* The new function asplit() allow splitting an array or matrix by
its margins.
* New functions errorCondition() and warningCondition() provide a
convenient way to create structured error and warning objects.
.Deprecated() now signals a warning of class "deprecatedWarning",
and .Defunct() now signals an error of class "defunctError".
* Many 'package not found' errors are now signaled as errors of
class "packageNotFoundError".
* As an experimental feature, when loadNamespace() fails because
the requested package is not available the error is initially
signaled with a retry_loadNamespace restart available. This
allows a calling handler to try to install the package and
continue.
* S3method() directives in NAMESPACE can now also be used to
perform _delayed_ S3 method registration.
* Experimentally, setting environment variable
_R_CHECK_LENGTH_1_LOGIC2_ will lead to warnings (or errors if the
variable is set to a 'true' value) when && or || encounter and
use arguments of length more than one.
* Added "lines" and "chars" coordinate systems to grconvertX() and
grconvertY().
* getOption() is more efficient notably for the rare case when
called with two arguments, from several contributors in PR#17394.
* In .col(dim) and .row(dim), dim now may also be an integer-valued
"double".
* sQuote() and dQuote() get an explicit q argument with obvious
default instead of using getOption("fancyQuotes") implicitly and
unconditionally.
* unzip() can list archives with comments and with spaces in file
names even using an external unzip command.
* Command line completion has a new setting rc.settings(dots =
FALSE) to remove ... from the list of possible function
arguments.
* library() no longer checks packages with compiled code match
R.version$platform. loadNamespace() never has, and increasingly
the 'canonical name' does not reflect the important
characteristics of compiled code.
* The primitive functions drop() and unclass() now avoid
duplicating their data for atomic vectors that are large enough,
by returning ALTREP wrapper objects with adjusted attributes.
R-level assignments to change attributes will also use wrapper
objects to avoid duplicating data for larger atomic vectors. R
functions like structure() and unname() will therefore not
duplicate data in these settings. Generic vectors as produced by
list() are not yet covered by this optimization but may be in due
course.
* In formals(), envir becomes an optional argument instead of being
hardwired.
* Instead of signalling an error for an invalid S4 object x, str(x)
now gives a warning and subsequently still shows most parts of x,
e.g., when slots are missing.
* gamma(x) and lgamma(x) no longer warn when correctly returning
Inf or underflowing to zero. This helps maximum likelihood and
similar computations.
* convertColor() is now vectorized, so a lot faster for converting
many colours at once. The new argument vectorized to
colorConverter() ensures that non-vectorized colour converters
still work. (Thanks to Brodie Gaslam.)
* download.file() and url() get new argument headers for custom
HTTP headers, e.g., allowing to perform basic http
authentication, thanks to a patch contributed by G'abor Cs'ardi.
* File-based connection functions file(), gzfile(), bzfile() and
xzfile() now signal an error when used on a directory.
* For approx(), splinefun() _etc_, a new setting ties =
c("ordered", <fun>) allows skipping the sorting and still treat
ties.
* format(x) gives a more user friendly error message in the case
where no method is defined. A minimal method is provided in
format.default(x) when isS4(x) is true.
* which(x) now also works when x is a long vector, thanks to
Suharto Anggono's PR#17201. *NB*: this may return a double
result, breaking the previous guarantee of an integer result.
* seq.default() is more careful to return an integer (as opposed to
double) result when its arguments are large and/or classed
objects; see comment #9 of Suharto Anggono's PR#17497.
* The plot() method for lm and glm fits, plot.lm(), gains a new
option iter.smooth with a default of 0 for binomial fits, no
longer down-weighting when smoothing the residuals.
* zip() passes its list of files _via_ standard input to the
external command when too long for the command line (on some
platforms).
* data() gains an overwrite argument.
* t.test() now also returns the standard error (in list component
stderr).
* model.matrix(*, contrasts.arg = CC) now warns about invalid
contrasts.args.
* Performance of substr() and substring() has been improved.
* stopifnot() has been simplified thanks to Suharto Anggono's
proposals to become considerably faster for cheap expressions.
* The default 'user agent' has been changed when accessing http://
and https:// sites using libcurl. (A site was found which caused
libcurl to infinite-loop with the previous default.)
* sessionInfo() now also contains RNGkind() and prints it when it
differs from the default; based on a proposal and patch by Gabe
Becker in PR#17535. Also, RNGversion(getRversion()) works
directly.
* library() and require() now allow more control over handling
search path conflicts when packages are attached. The policy is
controlled by the new conflicts.policy option.
* barplot() gets a formula method, thanks to a patch proposal by
Arni Magnusson in PR#17521.
* pmax() and pmin(x) now also work for long vectors, thanks to
Suharto Anggono's PR#17533.
* bxp() now warns when omitting duplicated arguments.
* New hcl.colors() function to provide wide range of HCL-based
colour palettes with much better perceptual properties than the
existing RGB/HSV-based palettes like rainbow().
Also a new hcl.pals() function to list available palette names
for hcl.colors().
Contributed by Achim Zeileis.
* The default colours for image() and filled.contour() are now
based on hcl.colors().
* The palette-generating functions rainbow(), gray.colors(), etc.
get a new rev argument to facilitate reversing the order of
colors.
* New str2lang() and str2expression() as streamlined versions of
parse(text=., keep.source=FALSE) allow to abstract typical call
constructions, e.g., in formula manipulations. (Somewhat
experimental)
* Add update_PACKAGES() for incrementally updating a package
repository index, instead of rebuilding the index from scratch.
Thanks to Gabe Becker in PR#17544 for the patch, based on part of
his switchr package.
INSTALLATION on a UNIX-ALIKE:
* The options selected for the C++ compiler default to the C++11
standard if supported, otherwise to the C++98 standard.
* Visibility macros such as C_VISIBILITY can now be user-set
(including to empty), e.g. in config.site.
* Macro FCLIBS, which has sometimes been needed on Solaris, has
been renamed to FCLIBS_XTRA.
* Macro F77 is always set to the value of FC, so the latter should
be set to user-select the Fortran compiler for both fixed-form
and free-form Fortran. In particular, gfortran is now the first
choice for F77, not f95.
Macros FFLAGS and FCFLAGS remain distinct to allow for a compiler
which needs a flag to select free- or fixed-form Fortran (most
use the source-file extension to choose: .f is fixed-form and
.f90 and .f95 are free-form).
If only one of them is set, its value is used for both.
* The special-casing of CFLAGS, CXXFLAGS and FFLAGS for Intel
compilers on Linux has been removed: we do not have recent
experience but the generic defaults now chosen are the same as
those previously special-cased for x86_64.
If necessary, override the defaults on the configure command line
or in file config.site.
* Long-untested configure support for HP-UX and very old versions
of Linux has been removed.
* configure --with-blas (without specifying a value) includes
OpenBLAS in its search (before ATLAS and a generic BLAS). This
follows recent versions of the ax_blas autoconf macro.
* The configure macro MAKEINFO has been updated to TEXI2ANY.
* Support for make install-strip has been enhanced.
PACKAGE INSTALLATION:
* Source package installation is by default 'staged': the package
is installed into a temporary location under the final library
directory and moved into place once the installation is complete.
The benefit is that partially-installed packages are hidden from
other R sessions.
The overall default is set by environment variable
R_INSTALL_STAGED. R CMD INSTALL has new options --staged-install
and --no-staged-install, and packages can use the StagedInstall
field in their DESCRIPTION file to opt out. (That opt-out is a
temporary measure which may be withdrawn in future.)
Staged installation requires either --pkglock or --lock, one of
which is used by default.
* The interpretation of source code with extension .f is changing.
Previously this denoted FORTRAN 77 code, but current compilers no
longer have a FORTRAN 77 mode and interpret it as 'fixed-form'
Fortran 90 (or later where supported) code. Extensions .f90 and
.f95 continue to indicate 'free-form' Fortran code.
Legal FORTRAN 77 code is also legal fixed-form Fortran 9x;
however this change legitimizes the use of later features, in
particular to replace features marked 'obsolescent' in Fortran 90
and 'deleted' in Fortran 2018 which gfortran 8.x and later warn
about.
* Packages containing files in the src directory with extensions
.f90 or .f95 are now linked using the C or C++ compiler rather
than the Fortran 9x compiler. This is consistent with fixed-form
Fortran code and allows mixing of C++ and free-form Fortran on
most platforms.
Consequentially, a package which includes free-form Fortran 9x
code which uses OpenMP should include SHLIB_OPENMP_CFLAGS (or the
CXXFLAGS version if they also include C++ code) in PKG_LIBS
rather than SHLIB_OPENMP_FCFLAGS - fortunately on almost all
current platforms they are the same flag.
* Macro PKG_FFLAGS will be used for the compilation of both
fixed-form and free-form Fortran code unless PKG_FCFLAGS is also
set (in src/Makevars or src/Makevars.win).
* The make macro F_VISIBILITY is now preferred for both fixed-form
and free-form Fortran, for use in src/Makevars and similar.
* R CMD INSTALL gains a new option --strip which (where supported)
strips installed shared object(s): this can also be achieved by
setting the environment variable _R_SHLIB_STRIP_ to a true value.
The new option --strip-lib attempts stripping of static and
shared libraries installed under lib.
These are most useful on platforms using GNU binutils (such as
Linux) and compiling with -g flags.
* There is more support for installing UTF-8-encoded packages in a
strict Latin-1 locale (and probably for other Latin locales):
non-ASCII comments in R code (and NAMESPACE files) are worked
around better.
UTILITIES:
* R CMD check now optionally checks makefiles for correct and
portable use of the SHLIB_OPENMP_*FLAGS macros.
* R CMD check now evaluates \Sexpr{} expressions (including those
in macros) before checking the contents of Rd files and so
detects issues both in evaluating the expressions and in the
expanded contents.
* R CMD check now lists missing packages separated by commas and
with regular quotes such as to be useful as argument in calling
install.packages(c(..)); from a suggestion by Marcel Ramos.
* tools::Rd2latex() now uses UTF-8 as its default output encoding.
* R CMD check now checks line endings of files with extension .hpp
and those under inst/include. The check now includes that a
non-empty file is terminated with a newline.
R CMD build will correct line endings in such files.
* R CMD check now tries re-building all vignettes rather than
stopping at the first error: whilst doing so it adds 'bookmarks'
to the log. By default (see the 'R Internals' manual) it
re-builds each vignette in a separate process.
It now checks for duplicated vignette titles (also known as
'index entries'): they are used as hyperlinks on CRAN package
pages and so do need to be unique.
* R CMD check has more comprehensive checks on the data directory
and the functioning of data() in a package.
* R CMD check now checks autoconf-generated configure files have
their corresponding source files, including optionally attempting
to regenerate them on platforms with autoreconf.
* R CMD build has a new option --compression to select the
compression used for the tarball.
* R CMD build now removes src/*.mod files on all platforms.
C-LEVEL FACILITIES:
* New pointer protection C functions R_PreserveInMSet and
R_ReleaseFromMSet have been introduced to replace UNPROTECT_PTR,
which is not safe to mix with UNPROTECT (and with
PROTECT_WITH_INDEX). Intended for use in parsers only.
* NAMEDMAX has been raised to 7 to allow further protection of
intermediate results from (usually ill-advised) assignments in
arguments to BUILTIN functions. Properly written package code
should not be affected.
* R_unif_index is now considered to be part of the C API.
* R_GetCurrentEnv() allows C code to retrieve the current
environment.
DEPRECATED AND DEFUNCT:
* Argument compressed of untar() is deprecated - it is only used
for external tar commands which increasingly for extraction
auto-detect compression and ignore their zjJ flags.
* var(f) and hence sd(f) now give an error for factor arguments;
they gave a deprecation warning since R 3.2.3, PR#16564.
* Package tools' vignetteDepends() has been deprecated (it called a
function deprecated since Feb 2016), being partly replaced by
newly exported vignetteInfo().
* The f77_f2c script has been removed: it no longer sufficed to
compile the .f files in R.
* The deprecated legacy support of make macros such as CXX1X has
been removed: use the CXX11 forms instead.
* Make macro F77_VISIBILITY is deprecated in favour of
F_VISIBILITY.
* Make macros F77, FCPIFCPLAGS and SHLIB_OPENMP_FCFLAGS are
deprecated in favour of FC, FPICFLAGS and SHLIB_OPENMP_FFLAGS
respectively.
* $.data.frame had become an expensive version of the default
method, so has been removed. (Thanks to Radford Neal for picking
this up and to Duncan Murdoch for providing a patch.)
BUG FIXES:
* replayPlot(r) now also works in the same R session when r has
been "reproduced" from serialization, typically after saving to
and reading from an RDS file.
* substr() and substring() now signal an error when the input is
invalid UTF-8.
* file.copy() now works also when its argument to is of length
greater than one.
* mantelhaen.test() no longer suffers from integer overflow in
largish cases, thanks to Ben Bolker's PR#17383.
* Calling setGeneric("foo") in a package no longer fails when the
enclosing environment of the implicit generic foo() is
.GlobalEnv.
* untar(file("<some>.tar.gz"), *) now gives a better error message,
suggesting to use gzfile() instead.
* Method dispatch uses more relevant environments when looking up
class definitions.
* The documentation for identify() incorrectly claimed that the
indices of identified points were returned in the order that the
points were selected. identify() now has a new argument order to
allow the return value to include the order in which points were
identified; the documentation has been updated. Reported by
Richard Rowe and Samuel Granjeaud.
* order(...., decreasing=c(TRUE, FALSE)) could fail in some cases.
Reported from StackOverflow via Karl Nordstr"om.
* User macros in Rd files now accept empty and multi-line
arguments.
* Changes in print.*(), thanks to Lionel Henry's patches in
PR#17398:
* Printing lists, pairlists or attributes containing calls with
S3 class no longer evaluate those.
* Printing S4 objects within lists and pairlists dispatches
with show() rather than print(), as with auto-printing.
* The indexing tags (names or [[<n>]]) of recursive data
structures are now printed correctly in complex cases.
* Arguments supplied to print() are now properly forwarded to
methods when printing lists, pairlists or attributes
containing S3 objects.
* The print parameters are now preserved when printing S3
objects or deparsing symbols and calls. Previously, printing
lists containing S3 objects or expressions would reset these
parameters.
* Printing lists, pairlists or attributes containing functions
now uses srcref attributes if present.
* Calling install.packages() with a length zero pkgs argument now
is a no-op (PR#17422).
* unlist(x) now returns a correct factor when x is a nested list
with factor leaves, fixing PR#12572 and PR#17419.
* The documentation help(family) gives more details about the aic
component, thanks to Ben Bolker's prompting.
* The documentation for attributes and `attributes<-` now gives x
as name of the first and main argument which the implementation
has been requiring, fixing PR#17434. For consistency, the first
argument name is also changed from obj to x for
`mostattributes<-`.
* strwidth() now uses par("font") as default font face (PR#17352).
* plot(<table>, log="x") no longer warns about log.
* The print() method for "htest" objects now formats the test
statistic and parameter directly and hence no longer rounds to
units _before_ the decimal point. Consequently, printing of
t.test() results with a small number of digits now shows
non-large df's to the full precision (PR#17444).
* kruskal.test() and fligner.test() no longer erroneously insist on
numeric g group arguments (PR#16719).
* Printing a news db via the browser now does a much better job
(PR#17433).
* print.aov() missed column names in the multivariate case due to
misspelling (reported by Chris Andrews).
* axis() now creates valid at locations also for small subnormal
number ranges in log scale plots.
* format.POSIXlt() now also recycles the zone and gmtoff list
components to full length when needed, and its internal C code
detects have_zone in more cases. In some cases, this changes its
output to become compatible with format.POSIXct().
* On Windows, detectCores() in package parallel now detects
processors in all processor groups, not just the group R is
running in (impacts particularly systems with more than 64
logical processors). Reported by Arunkumar Srinivasan.
* On Windows, socketSelect() would hang with more than 64 sockets,
and hence parallel::clusterApplyLB() would hang with more than 64
workers. Reported by Arunkumar Srinivasan.
* as(1L, "double") now does coerce (PR#17457).
* lm.influence(), influence.measures(), rstudent() etc now work
(more) correctly for multivariate models ("mlm"), thanks to
(anonymous) stackoverflow remarks.
* sample.int(2.9, *, replace=TRUE) again behaves as documented and
as in R < 3.0.0, namely identically to sample.int(2, ..).
* Fixes to convertColor() for chromatic adaptation; thanks to
Brodie Gaslam PR#17473.
* Using \Sexpr[stage=install]{..} to create an Rd section no longer
gives a warning in R CMD check; problem originally posted by
G'abor Cs'ardi, then reported as PR#17479 with a partial patch by
Duncan Murdoch.
* Parse data now include a special node for equal assignment.
* split.default() no longer relies on [[<-(), so it behaves as
expected when splitting an object by a factor with the empty
string as one of its levels. Thanks to Brad Friedman for the
report.
* Line numbers in messages about .Rd files are now more reliable,
thanks to a patch from Duncan Murdoch.
* In the numeric method for all.equal(), a numeric scale argument
is now checked to be positive and allowed to be of length > 1.
(The latter worked originally and with a warning in recent
years).
* Deferred string conversions now record the OutDec option setting
when not equal to the default. Reported by Michael Sannella.
* When y is numeric and f a factor, plot(y ~ f) nicely uses "y" and
"f" as y- and x-labels. The more direct boxplot(y ~ f) now does
too. The new argument ann = FALSE may be used to suppress these.
* Subassignment to no/empty rows of a data frame is more consistent
and typically a no-op in all cases instead of sometimes an error;
part of Emil Bode's PR#17483.
* Calls like formatC(*, zero.print = "< 0.001") no longer give an
error and are further improved via new optional argument
replace.zero. Reported by David Hugh-Jones.
* methods::formalArgs("<fn>") now finds the same function as
formals("<fn>"), fixing Emil Bode's PR#17499.
* The methods package better handles duplicated class names across
packages.
* The default method of seq() now avoids integer overflow, thanks
to the report and "cumsum" patch of Suharto Anggono's PR#17497.
* sub() no longer loses encodings for non-ASCII replacements
(PR#17509).
* Fix for rotated raster image on X11 device. (Partial fix for
PR#17148; thanks to Mikko Korpela).
* formula(model.frame(frml, ..)) now returns frml in all cases,
thanks to Bill Dunlap. The previous behavior is available as
DF2formula(<model.frame>).
* ar.ols() also returns scalar var.pred in univariate case
(PR#17517).
* normalizePath() now treats NA path as non-existent and normalizes
it to NA. file.access() treats NA file name as non-existent.
file.edit() and connection functions such as file() now treat NA
file names as errors.
* The internal regularize.values() auxiliary of approx(),
splinefun() etc now warns again when there are ties and the
caller did not specify ties. Further, it no longer duplicates x
and y unnecessarily when x is already sorted (PR#17515).
* strtoi("", base) now gives NA on all platforms, following its
documentation. Reported by Michael Chirico.
* In the definition of an S4 class, prototype elements are checked
against the slots of the class, with giving a prototype for an
undefined slot now being an error. (Reported by Bill Dunlap.)
* From setClassUnion(), if environment variable
_R_METHODS_SHOW_CHECKSUBCLASSES is set to true, the internal
.checkSubclasses() utility prints debugging info to see where it
is used.
* max.col(m) with an m of zero columns now returns integer NA
(instead of 1).
* axTicks() no longer returns small "almost zero" numbers (in
exponential format) instead of zero, fixing Ilario Gelmetti's
PR#17534.
* isSymmetric(matrix(0, dimnames=list("A","b"))) is FALSE again, as
always documented.
* The cairo_pdf graphics device (and other Cairo-based devices) now
clip correctly to the right and bottom border.
There was an off-by-one-pixel bug, reported by Lee Kelvin.
* as.roman(3) <= 2:4 and all other comparisons now work, as do
group "Summary" function calls such as max(as.roman(sample(20)))
and as.roman(NA). (Partly reported by Bill Dunlap in PR#17542.)
* reformulate("x", response = "sin(y)") no longer produces extra
back quotes, PR#17359, and gains new optional argument env.
* When reading console input from stdin with re-encoding (R
--encoding=enc < input) the code on a Unix-alike now ensures that
each converted input line is terminated with a newline even if
re-encoding fails.
* as.matrix.data.frame() now produces better strings from logicals,
thanks to PR#17548 from Gabe Becker.
* The S4 generic signature of rowSums(), rowMeans(), colSums() and
colMeans() is restricted to "x".
* match(x, tab) now works for long _character_ vectors x, thanks to
PR#17552 by Andreas Kersting.
* Class unions are unloaded when their namespace is unloaded
(PR#17531, adapted from a patch by Brodie Gaslam).
* selectMethod() is robust to ANY-truncation of method signatures
(thanks to Herve Pages for the report).

Upstream changes:
CHANGES IN R 3.5.3:
INSTALLATION on a UNIX-ALIKE:
* Detection of flags for C++98/11/14/17 has been improved: in
particular if CXX??STD is set, it is tried first with no
additional flags.
PACKAGE INSTALLATION:
* New macro F_VISIBILITY as an alternative to F77_VISIBILITY. This
will become the preferred form in R 3.6.0.
BUG FIXES:
* writeLines(readLines(fnam), fnam) now works as expected, thanks
to Peter Meissner's PR#17528.
* setClassUnion() no longer warns, but uses message() for now, when
encountering "non local" subclasses of class members.
* stopifnot(exprs = T) no longer fails.

Upstream changes:
CHANGES IN R 3.5.2:
PACKAGE INSTALLATION:
* New macro CXX_VISIBILITY analogous to C_VISIBILITY (which several
packages have been misusing for C++ code) for the default C++
compiler (but not necessarily one used for non-default C++
dialects like C++14).
TESTING:
* The random number generator tests in tests/p-r-random-tests.R no
longer fail occasionally as they now randomly sample from
"certified" random seeds.
BUG FIXES:
* The "glm" method of drop1() miscalculated the score test
(test="Rao") when the model contained an offset.
* Linear multiple empty models such as lm(y ~ 0) now have a
correctly dimensioned empty coefficient matrix; reported by Brett
Presnell.
* vcov(<empty mlm>) and hence confint() now work (via a consistency
change in summary.lm()).
* confint(<multiple lm()>) now works correctly; reported on R-devel
by Steven Pav.
* quade.test() now also works correctly when its arguments are not
yet sorted along groups, fixing PR#15842.
* Installation on a Unix-alike tries harder to link to the pthread
library where required (rather than relying on OpenMP to provide
it: configuring with --disable-openmp was failing on some Linux
systems).
* The data.frame method for print(x) is fast now also for large
data frames x and got an optional argument max, thanks to
suggestions by Juan Telleria.
* hist() no longer integer overflows in very rare cases, fixing
PR#17450.
* untar() ignored a character compressed argument: however many
external tar programs ignore the flags which should have been set
and automagically choose the compression type, and if appropriate
gzip or bzip2 compression would have been chosen from the magic
header of the tarball.
* zapsmall(x) now works for more "number-like" objects.
* The tools-internal function called from R CMD INSTALL now gets a
warnOption = 1 argument and only sets options(warn = warnOption)
when that increases the warning level (PR#17453).
* Analogously, the tools-internal function called from R CMD check
gets a warnOption = 1 argument and uses the larger of that and
getOption("warn"), also allowing to be run with increased warning
level.
* Parse data now have deterministic parent nodes (PR#16041).
* Calling match() with length one x and POSIXlt table gave a
segfault (PR#17459).
* Fork clusters could hang due to a race condition in cluster
initialization (makeCluster()).
* nextn(n) now also works for larger n and no longer loops
infinitely for e.g, n <- 214e7.
* cooks.distance() and rstandard() now work correctly for multiple
linear models ("mlm").
* polym() and corresponding lm() prediction now also work for a
boundary "vector" case fixing PR#17474, reported by Alexandre
Courtiol.
* With a very large number of variables terms() could segfault
(PR#17480).
* cut(rep(0, 7)) now works, thanks to Joey Reid and Benjamin Tyner
(PR#16802).
* download.file(*, method = "curl", cacheOK = FALSE) should work
now on Windows, thanks to Kevin Ushey's patch in PR#17323.
* duplicated(<dataframe with 'f'>) now works, too, thanks to
Andreas Kersting's PR#17485; ditto for anyDuplicated().
* legend(*, cex = 1:2) now works less badly.
* The print() method for POSIXct and POSIXlt now correctly obeys
getOption("max.print"), fixing a long-standing typo, and it also
gets a corresponding optional max argument.
* Unserialization of raw vectors serialized in ASCII representation
now works correctly.
* <data frame>[TRUE, <new>] <- list(c1, c2) now works correctly,
thanks to Suharto Anggono's PR#15362 and Emil Bode's patch in
PR#17504.
* seq.int(*, by=by, length=n) no longer wrongly "drops fractional
parts" when by is integer, thanks to Suharto Anggono's report
PR#17506.
* Buffering is disabled for file() connections to non-regular files
(like sockets), as well as fifo() and pipe() connections. Fixes
PR#17470, reported by Chris Culnane.
