This blog is updated daily..
A general description is here.
The "data.frame" and "factor" methods for [[ now support
the 'exact' argument introduced in 2.6.0.
plot.lm() gains a new argument 'cex.caption' to allow the
size of the captions to be controlled.
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.
embedFonts(), bitmap() and dev2bitmap() explicitly turn off
auto-rotation in Ghostscript when generating PDF.
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.
Deparsing will (if option warnIncomplete is set) warn on
strings longer than the parser limit (8192 bytes).
url() now uses the UserAgent header in http transactions in
the same way as download.file() (making use of option
"HTTPUserAgent").
iconv() is again able to translate character strings with
embedded nuls (such as those in UCS-2).
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.
Builds on Mac OS X 10.4 or higher now allocate enough space
in the binary headers to relocate dependent libraries into the
framework.
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.
object.size() had slightly too low a size for objects of type "S4".
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.
An event handling issue caused autorepeat functions to
misbehave with tcltk (notably scrollbars).
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.
curve() with unspecified 'from', 'to' and 'xlim' now reuses the
previous x limits, and not slightly larger ones.
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)
'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.
DF[i, j] failed in 2.6.0 if j was a logical vector selecting a
single column.
Unix x11() would fail if a valid 'display' was specified but
DISPLAY was unset. (PR#10379)
postscript() was not always ignoring .Postscript.Options in
the workspace (where it should not have occurred).
help.search() would give an error if it found a badly
installed package, even if 'package' was not specified.
tclServiceMode() (package tcltk) now works under Unix-alikes.
(Although documented, it used only to work under Windows.)
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.]
Deliberately using malformed source attributes no longer
causes deparsing/printing of functions to crash R. (PR#10437)
R CMD check and R CMD INSTALL now work with (some) directory
names containing spaces.
