* Bug-fix release.
|
|
* The core LP solver based on the dual simplex method was
re-implemented and now it provides both phases I and II.
* New API routines.
* For description of these new routines see the reference manual
included in the distribution.
* The following API routines are deprecated:
lpx_scale_prob, lpx_std_basis, lpx_adv_basis, lpx_cpx_basis.
* Necessary changes were made in memory allocation routines to
resolve portability issues for 64-bit platforms.
* New version of the routine lpx_write_pb to write problem data
in OPB (pseudo boolean format) was added to the package.
* Two new makefiles were added to build the package for 32- and
64-bit Windows with Microsoft Visual Studio Express 2008.
* Two new makefiles were added to build the package with Digital
Mars C/C++ 8.50 and Open Watcom C/C++ 1.6 (for 32-bit Windows).

NEW FEATURES
o sprintf() returns elements of the result in UTF-8 when the
format or any character input has a corresponding element
declared as UTF-8. Similarly for paste(), elements of the
result are in UTF-8 when any input to that element is declared
as UTF-8.
o axis() has new arguments 'col.ticks' and 'lwd.ticks' to allow
the colour and line width of ticks to be set separately from
that of the line (e.g. to set one or the other to transparent
or zero width).
o legend() has a new argument 'box.col' to set the colour of the
enclosing box.
o legend() gains a 'xpd' argument to make it easier to place a
legend in the margins or outer margins.
o stripchart() now passes '...' to title() (as well as to
plot.default() and axis()). (Wish of PR#12202)
o help.search() has new argument 'searchEngine' to go
directly to the search form: this is needed by users of
Firefox 3 to workaround a bug in interpreting the search
results pages.
+ BUG FIXES
2.7.1 NEW FEATURES
o tools::texi2dvi() has a new argument 'texinputs' to allow the
TeX and bibtex input paths to be specified (even on MiKTeX).
o dev.copy2pdf() gains an 'out.type' argument to allow it to be
used with cairo_pdf() or quartz(type = "pdf").
o poly() has additional checks against user error (as in PR#11243).
o The Mac OS quartz() device draws contiguous lines much faster.
o A field containing just a sign is no longer regarded as numeric
(it was on all platforms in 2.7.0, but not on most in earlier
versions of R). Similarly, '.' is now always non-numeric.
o CITATION files are now read in Latin-1: quite a few were
failing if used in a multibyte locale such as UTF-8.
o The DESCRIPTION file of a package can specify an 'OS_type' field
as either 'unix' or 'windows' to confine installation to that
OS type.
o HoltWinters() now uses optimize() rather than optim for
one-parameter problems which should be more reliable (PR#11469).
o axis() now respects the setting of par("xpd") when clipping.
o The 'factor' method of format() now preserves names, dims and
dimnames in the same way as for character and numeric inputs.
(PR#11512)
o read.DIF(*, transpose=TRUE) now allows to correctly read DIF files
produced by some versions of Excel.
DEPRECATED & DEFUNCT
o The use of unserialize() on character strings is deprecated:
that was a format used in R < 2.4.0.
o The use of embedded nuls in character strings is deprecated:
They will no longer be allowed in R 2.8.0.
UTILITIES
o R CMD check checks for possible check directories in the
sources -- in mid-2008 there were about 20 examples on CRAN.
o R CMD build tries harder to clean up the inst/doc directory
from the remnants of earlier builds.
It also removes any directories with extension .Rcheck, and
files .DS_Store and ._* (created by tar on Mac OS X under some
circumstances: it now sets environment variables to ask for
such files not to be created by that tar.)

* glpspx.h, glpspx03.c, glpapi06.c

replaced by a new implementation (spx_primal), which currently
provides the same features as the old version.
* glpmpl01.c, glpmpl03.c
Some changes were made in the MathProg translator to allow <,
<=, >=, and > on comparing symbolic values.
* glplpx10.c

Test suite was sub()ifying argument to sumnuminit().
Test suite would not correctly sub()ify intnum() if limits had "()".
Test suite calculated Pi Euler too early; Now only these fail
t/55_intnum.t 51 1 1.96% 12
t/55_ploth.t 34 1 2.94% 4
# eval-noans: $oo=[ PARI(1) ];
# eval-noans: setprecision(96)
# eval-noans: $tab=intfuncinit($t,[-$oo,4.5],[$oo,4.5], sub{gamma(2+ I*$t)**3},1);
# eval: intmellininvshort(2,4,$tab)-$A

Why this succeeds?
# eval: intnum($x,-1,1, sub{intnum($y,-sqrt(1-$x**2),sqrt(1-$x**2),$x**2+$y**2,$tab)},$tab)- Pi/2
Actually, $x**2+$y**2 is converted to a string as in '0.09+y^2',
which is interpreted by GP/PARI.
Add warnings to the test suite for detection of #@_
in Perl-in-PARI-in-Perl calls.

Pkgsrc change:
o Convert to using Module::Build.
Upstream changes:
Changes in v2.05 - leto
Fri Feb 29 21:58:47 EST 2008
----------------------------
* fix accidental use of "our" that broke old (like 5.5) Perl's
Thanks to srezic@cpan.org for the first FAILed report
* added $matrix->display_precision($n) to easily change the output
to something a bit easier to read
$a->display_precision(0)
is useful for printing integer matrices nicely
* NEED print_precision() docs near stringify
* t/display_precision.t created
* example/ directory created with some benchmark scripts
Changes in v2.04 - leto
Sat Feb 23 20:59:08 EST 2008
---------------------------
* fixed pod errors
* $a->length does row+col vectors now
* converted all tests except ext1.t to Test::More and added
some overall Kwalitee
* fixed error with doing $string = $matrix . "\nStuff\n";
* new funcion new_tridiag
* $matrix->min and $matrix->max now return the min/max element of a matrix
* new function new_random added which looks like (with default
options shown)
# returns $n x $m matrix of real numbers between 0 and 10
new_random($n,$m, { symmetric => 0, tridiag => 0, bounded_by => [0,10], integer => 0 )
new_random($n, %options ) # returns a square matrix
This has proven to be pretty useful in the unit tests of
Math::MatrixReal so I figured others may want an easy way to
generate a random matrix of your own flavor
* t/rand.t created
* t/tridiag.t created
* t/stringify.t created
* t/minimax.t created
* t/positive.t created
* t/gsm.t created
* t/similar.t created
Changes in v2.03 - leto
Sun Jan 27 13:19:55 EST 2008
---------------------------
* now using Module::Build, so Math::MatrixReal should in theory be able to
compile on systems without make, please test and let me know!
* new concatenation operator ".", i.e $c = $a . $b concatenates two
matrices side-by-side
* t/concat.t created
* new function assign_row
* beginning of a test suite overhaul (converting to Test::More )
Changes in v2.02 - leto
Sat Jun 09 12:29:08 EDT 2007
----------------------------
* Fixed the overloading for the division operator which did
not recognize $a/2, reported by Daniel Brooks <db48x@yahoo.com>
* Added support for matrix division notation, so that $a/$b =
$a*$b**(-1) when $a and $b are square matrices
* t/div.t created

which was on by accident.
+ Added "Warning about Office Service Pack 3" section to the
docs to explain Excel warnings with duplicate data.
+ Expanded "Dates and Time in Excel" section of the docs.
+ Added isa() to _process_images() to allow subclassing.

Pure Perl implementation of the Mersenne Twister algorithm as
implemented in C/XS in Math::Random::MT. The output is identical
to the C/XS version. The Mersenne Twister is a 32 bit pseudorandom
number generator developed by Makoto Matsumoto and Takuji Nishimura.
The algorithm is characterised by a very uniform distribution but
is not cryptographically secure. What this means in real terms is
that it is fine for modeling but no good for crypto.

these options are only used by R.app on Mac OS X

This program is used to find Mersenne Prime numbers. See
http://www.utm.edu/research/primes/mersenne.shtml for a good
description of Mersenne primes. Mersenne numbers can be proved
composite (not prime) by either finding a factor or by running
a Lucas-Lehmer primality test.
