I've rolled up R-2.7.2.tar.gz a short while ago.

This is intended as a wrap-up release containing all known fixes to issues with the 2.7.x series. 

See the full list of changes below.

You can get it (in a short while) from


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:



    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.


    o	Plotmath computed the glyph metrics for the wrong character (and
	perhaps for a non-existent one) if this was a single-byte
	character with the top bit set.  An example was	symbol("\300").

    o	sink() and cat() could divert output to a non-writable connection.

    o	phyper(x, 0,0,0) no longer hangs for huge x and gives 1 for x >= 0.

    o	plnorm(x, ..., log.p=TRUE) is now correct for x <= 0. (PR#11867)

    o	<data.frame>[, ch] gives an error (again!) when ch is a string not
	exactly matching the column names, thanks to an oral bug report by
	Matthew Dowle.

    o	data.frame(x=1:2, y=3:4, row.names=c("a","NA"))[c(2,NA),] has
	correct row names c("NA,"NA.1") again.

    o	The GUI data editor for dataframes did not handle escape
	characters in entries properly. (PR#11897)

    o	PCRE has been updated to 7.7 (bugfix release).

    o	package.skeleton() wrongly warned about invalid code_files names
	when these were not in the current directory.

    o	shapiro.test(c(0,0,1)) now has P value >= 0 (instead of barely

    o	assign() now warns if given a character vector of length > 1,
	rather than silently taking the first element.

    o	rcond(<exactly singular matrix>) now gives 0 instead of an error.

    o	There was a memory leak in C function ucstoutf8 used by some
	graphics devices.

    o	Plots of profile.mle() objects (package 'stats4') were
	misbehaving when the 'which' argument had been used in their

    o	dnbinom(x, size, mu=*, ..) is now more accurate for very large
	'size'.  The same applies to pnbinom() and rnbinom().

    o	axis() was ignoring par() mgp[3] if mgp was set in-line.

    o	Closing an X11 View() or dataentry window via its frame's
	close control now works better on some window managers.

    o	Calling lapply() was not handling method dispatch correctly for
	is.numeric(), is.matrix(), is.array(), log() and the Math2
	group.  This affected data.matrix() which incorrectly regarded
	"Date" and "POSIXct" objects as numeric, and has been adjusted
	to do so as exceptions.

    o	package.skeleton() was not looking for non-function objects in
    	its 'environment' argument.

    o	nls() was only finding its 'weights' argument in the case when
    	all the variables in the formula were of the same length and
    	hence that model.frame() could be used.

	It was silently ignoring 'subset' and 'na.action' except in
	that case.  Now they are ignored only if 'data' is a list and
	variables taken from 'data' are not all of the same length,
	in which case a warning is given.

    o	The 'mle' confint() method now takes 'level' into account when
	setting 'alpha' for the profile.

    o	within() was not handling correctly expressions that produced
	NULL columns.  (PR#11131)

    o	dev.print() and dev.copy2{eps,pdf}() now ensure that the current
	device is restored as the active device even if an error
	occurs. (PR#9801)

    o	as.Date() could fail to convert character strings representing
	days on which midnight did not exist in the current timezone
	(as happened in parts of Africa on 1960-01-01).

    o	The automatic placement of legend() with 'title' and a
	reversed 'x' axis was incorrect. (PR#12019)

    o	The use of multiple packages in 'LinkingTo' works again, and
    	now works when the dependent packages are in the library to be
    	installed to (but not in the library path seen by R --vanilla).

    o	bxp() (and hence boxplot) now respects in-line graphical
	parameters 'xaxp'/'yaxp' as appropriate.  (PR#11463)

    o	barplot(log = "y") failed if there were NAs in the 'height'
	argument.  (PR#11585)

    o	pbeta() is more accurate in some cases with extreme values of
	'ncp'.  (PR#11277).

    o	edit.data.frame() no longer fails if called on a 0-column
	data frame and no column is created.

    o	pchisq(x, df=0) was always one even for x < 0; similarly for
	pgamma(x, alpha=0).

    o	add1() and drop1() now return a P-value of NaN in cases with
	df=0 for test="Chisq" (they gave NaN until pchisq was altered
	in R 2.6.2).

    o	The default methods of drop1() and add1() now re-evaluate in the
	object's formula environment, rather than simply in the parent
	(informal bug report by Werner Stahel).

    o	The undocumented limit of 8191 bytes on comments (from # to
	the end of the line) in R code has been removed.

    o	qgamma() warns if used with shape < 1e-10, when it may be
 	unreliable.  (PR#12324)

    o	Installing a source package was not using the package's declared
	encoding (if any) as a default encoding for the help.search()
	database in Meta/hsearch.rds.  This could cause packages with
	a default encoding to have some of their entries rejected by
	help.search() in a multi-byte locale (such as a UTF-8 locale).

    o	duplicated() and unique() now handle 'incomparables' better,
    	and avoid occasional segfaults (PR#12551).

    o	data.frame(row.names=NULL) once again behaves differently from
	the default (as documented).

    o	plot(isoreg(x,y)) now plots the points correctly, also when 'x'
	is not sorted.
