S/R言語、S-PLUSコミュのR-2.6.1 is released

I've rolled up R-2.6.1.tar.gz a short while ago.

This is a maintenance release and fixes a number of mostly minor bugs
and platform issues, as well as a couple of major problems.

Probably, the most important issues were
- save-to-postscript on Windows
- tcltk event loop with X11
- build issue on recent MacOSX

See the full list of changes below.

You can get it (in a short while) from

http://cran.r-project.org/src/base/R-2/R-2.6.1.tar.gz

or wait for it to be mirrored at a CRAN site nearer to you. Binaries
for various platforms will appear in due course.

Here is the relevant bit of the NEWS file:

CHANGES IN R VERSION 2.6.1

NEW FEATURES

o The "data.frame" and "factor" methods for [[ now support
the 'exact' argument introduced in 2.6.0.

o plot.lm() gains a new argument 'cex.caption' to allow the
size of the captions to be controlled.

o A series of changes make the CHARSXP cache introduced in 2.6.0
faster (and in some cases many times faster) in sessions with
a large number (e.g. a million) of unique character strings,
and also if there are many empty strings.

o embedFonts(), bitmap() and dev2bitmap() explicitly turn off
auto-rotation in Ghostscript when generating PDF.

o The canonical architecture is no longer checked when loading
packages using a non-empty sub-architecture, since it is
possible to (e.g.) build packages for i386-pc-linux-gnu on both
that architecture and on x86_64-unknown-linux-gnu.

o Deparsing will (if option warnIncomplete is set) warn on
strings longer than the parser limit (8192 bytes).

o url() now uses the UserAgent header in http transactions in
the same way as download.file() (making use of option
"HTTPUserAgent").

BUG FIXES

o iconv() is again able to translate character strings with
embedded nuls (such as those in UCS-2).

o new.packages() and update.packages() failed when called on an
empty library, since old.packages() threw an error.
old.packages() now returns NULL (as documented) in that case.

o Builds on Mac OS X 10.4 or higher now allocate enough space
in the binary headers to relocate dependent libraries into the
framework.

o R CMD build now computes the exclusion list on the copy it
makes: this avoids problems if the original sources contain
symbolic links (which are resolved in the copy). Thanks to
Michael Lawrence for diagnosis and patch.

o object.size() had slightly too low a size for objects of type "S4".

o symbol() in plotmath expressions was only accepting valid
character strings, which made it impossible to specify symbols
such as aleph (obtained by symbol("\300")) in a UTF-8 locale.

o An event handling issue caused autorepeat functions to
misbehave with tcltk (notably scrollbars).

o plot(sin, -5, 5) gives ylab 'sin(x)' again, where it resulted
in 'x(x)' in 2.6.0. Further, plot(sin) again plots from
[0,1] also in cases where a previously used coordinate system
differs.

o curve() with unspecified 'from', 'to' and 'xlim' now reuses the
previous x limits, and not slightly larger ones.

o It was intended that R code filenames in packages should start
with an ASCII letter or digits (and R CMD INSTALL uses that),
but the test used in R CMD build ([A-Za-z0-9]) was
locale-specific (and excluded t to y in Estonian, for
example). (PR#10351)

o 'R CMD build' could misbehave when faced with files with CRLF
line endings *and* no line ending on the final line of the
file, removing the last byte of the file.

o DF[i, j] failed in 2.6.0 if j was a logical vector selecting a
single column.

o Unix x11() would fail if a valid 'display' was specified but
DISPLAY was unset. (PR#10379)

o postscript() was not always ignoring .Postscript.Options in
the workspace (where it should not have occurred).

o help.search() would give an error if it found a badly
installed package, even if 'package' was not specified.

o tclServiceMode() (package tcltk) now works under Unix-alikes.
(Although documented, it used only to work under Windows.)

o As Mac OS X 10.5.0 comes with incompatible /bin/sh shell, we
force SHELL=/bin/bash (which is ok) in that case. [Only for
2.6.x: another solution is used in 2.7.0.]

o Deliberately using malformed source attributes no longer
causes deparsing/printing of functions to crash R. (PR#10437)

o R CMD check and R CMD INSTALL now work with (some) directory
names containing spaces.

o choose(n, k) gave incorrect values for negative n and small k.

o plot.ts(x,y) could use wrong default labels; fixed thanks to
Antonio, Fabio di Narzo.

o reshape() got column names out of sync with contents in some
cases; found by Antonio, Fabio Di Narzo.

o ar(x) for short 'x' (i.e. length <= 10) could fail because the
default 'order.max' was >= length(x) which is non-sensical.

o Keyboard events in getGraphicsEvent() could cause stack
imbalance errors (PR#10453)
