NEW FEATURES
o new target for R installation testing : make strict-tests.
o symnum(x) now nicely codes logical x.
o convolve() has a new type = c("circular", "open", "filter")
argument allowing more than the only circular convolution.
o par(xpd) now has three settings: FALSE (clip to plot region),
TRUE (clip to figure region), or NA (clip to device region).
o zapsmall(x) works for complex x.
o new global variable R.version.string (for plots & reports).
Deprecated version & Version for new R.version & R.Version.
o R CMD Rd2dvi has builtin "Usage" help and works for multiple files.
Useful for automatic reference manual of a package.
(doc/manual/lib2tex is more efficient for installed packages, however).
BUG FIXES
o power() is now fully implemented and documented.
o A couple of problems with group generic operations.
o A bug which meant that it was not possible to add elements
to zero length lists in the obvious way has been fixed.
x <- list(); x[[1]] <- 10
x <- list(); x[["a"]] <- 11
both now work.
o save.image() ignored dot-names. (esp. .First())
o lab= argument to plot() misinterpreted by axis() via ... passing
o NULL labels in text() caused segfault
o matrix(f,...) with f a factor now coerces to character
o documentation errors for substitute and is.vector, minor fixups for
trig and nlm
o Background colours are set properly on X11 devices with
colortype="pseudo": sometimes they were not allocated separately.
o C() works (again?) for a single argument.
o is.na() didn't work properly for "list" arguments.
o symnum() sometimes failed with arrays of rank >= 3.
o in some cases one could get nonblack color instead of
black on 2nd x11() window.
o influence.measures(.) $ is.influential was wrong on the
cooks.distance.
o printing of complex NaN/Inf was wrong as well.
o printing of complex named vectors had a wrong initial space.
o allow trailing space in character->numeric coercion
o library() gave wrong "masked" warnings in some cases.
o par(xpd) semantics were not compatible with S.
o rect() output was not clipped in PostScript.
o par(pin=c(width, height)) was behaving as par(pin=c(width, width)).
o Non-blank separated data files didn't have their 1st field
handled properly.
o "aux" directory moved to "tools" to avoid difficulties on
Windows.
o structure() clobbered factors with missing levels.
o pmatch() misbehaved on duplicate matches.
o R CMD Rd2dvi <file.Rd> works again.
o logical binops tried to set time series parameters before dimensions.
o upped the BUFSIZE in model.c (NOT proper long-term solution).
o dput(), dump() and deparse() now always use DBL_DIG (=15) digits
for numeric formatting.
o chull() now works for vertical borders, such as in chull(c(1,1,2),3:1).
