[R] R 2.3.1 is released

From: Peter Dalgaard <p.dalgaard_at_biostat.ku.dk>
Date: Thu 01 Jun 2006 - 19:04:12 EST

I've rolled up R-2.3.1.tar.gz a short while ago. This version contains several minor fixups and removes a couple of bad bugs. 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-2.3.1.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.  

There is also a version split for floppies. (This will be the last time we build those.)

Here is the relevant bit of the NEWS file:

                CHANGES IN R VERSION 2.3.1 NEW FEATURES

    o	In lm() and glm(), offsets are allowed to be length 1 (and
	if so are replicated to the number of cases).

    o	The \uxxxx notation for Unicode characters in input strings
	can now be used on any platform which supports MBCS, even if
	the current locale is not MBCS (provided that the Unicode
	character is valid in the current character set).

    o	The quasibinomial() family now allows the "cauchit" link. (PR#8851)

    o	edit.data.frame() no longer (silently) coerces character columns
	to factor.


C-LEVEL FACILITIES

    o	The variables controlling stack checking are made available via
        Rinterface.h to front-ends embedding R: see 'Writing R Extensions'

    o	R_SignalHandlers (defined in Rinterface.h) can be set to 0 to
        suppress the R signal handlers in front-ends embedding R.


INSTALLATION CHANGES

    o	There have been a number of changes to help installation on
	platforms that no one had beta-tested.


- Changes related to older header files, e.g. on Redhat 8.0/9.

- Problems with 'make install' on older (<3) versions of bash
on Solaris and elsewhere.
- AIX 5.2/gcc issues with needing -lm when making modules X11
and vfonts.
- Some versions of Solaris and AIX had a fcntl.h that
redefined 'open' to be 'open64' and thereby broke compilation of src/main/connections.c and elsewhere. o 'make uninstall' works better on a build using a named subarchitecture.

BUG FIXES

    o	min(), max(), sum() and prod() gave nonsensical answers with
	an empty list or raw argument.

    o	sum() on a data frame did not allow multiple arguments.	 (PR#8385)

    o	charmatch() and pmatch() did not specify they applied only to
	character vectors.  Now they do, and attempt to coerce 'x' and
	'target' to character before attempting matching.

    o	The Summary() methods for data.frame, Date, POSIXct, POSIXlt
	and difftime all required an argument which can match 'x',
	although the generics did not.

    o	regexpr() now accepts 0-length 'text' inputs.

    o	help.search() no longer errors out on a wrongly installed package
	(with no "hsearch.rds" file).

    o	The LaTeX version of the package reference manual was omitting
	some topics, and was not sorting the foo-package topic first.

    o	Serializing (e.g. via save()) is better protected against C
	stack overflow, which will now abort the conversion but no
	longer crashes the R process on some platforms.

    o	rbind()ing dataframes with a single row could lead to a
	corrupt data frame (a problem with the fix to PR#8506).

    o	plot(lm(y ~ 1)) now works also for 'which = 5'.

    o	dbeta(0, 1, a, 0) now correctly gives 'a' (limit) instead of 0,
	and dbeta(0, a, b, ncp) now returns Inf instead of NaN.

    o	demo(Hershey) was failing on the Cyrillic octal codes in locales
	(e.g. UTF-8) in which these are invalid.

    o	mean() on an integer (or logical) vector was treating NAs as
	actual values (unless na.rm = TRUE).

    o	mean() on a complex vector was calculated incorrectly in
        code to improve precision (PR#8842, John Peters).

    o	Graphical parameters bg, cex, col, lty, and lwd were being
	checked as being of length one even by functions such as
	title() that ignored them.  (Functions such as lines() and
	points() allow them to be of length > 1, so they might be
	passed through ... to other high-level graphical functions
	which then used to reject them.)

    o	str() now is fast again for large character vectors.

    o	edit() would default the environment of a function to .BaseEnv,
	instead of to .GlobalEnv.

    o	lm() and glm() coerce their 'weights' and 'offset' values to
	vector to avoid problems with specifying them as 1D or n x 1
	arrays.

    o	image() with one or both axes on log scales would give a
	spurious warning; contour() would give an error.

    o	legend() with log axes would place the title in the wrong place.

    o	edit.data.frame() was not returning factors edited with
	factor.mode="numeric" to factors.

    o	edit.matrix() tried to set rownames and colnames from the
	original matrix even if the sizes had been altered, and
	ignored changes made to the column names.  edit.row.names has
	a more sensible default (if the rownames are non-NULL).

    o	bindingIsLocked() was returning invalid values of a logical
	vector on some platforms.

    o	merge.data.frame() did not make the column names unique (by
	appending elements of 'suffixes') when performing a Cartesian
	product.  (PR#8676)

    o	rbind.data.frame() matches up the names of columns (which was
	undocumented), but failed to do so when checking if it was
	dealing with a factor column.  (PR#8868)

	If rbind() was used on data frames with duplicated names it
	produced a corrupt data frame.

    o	dt(x, df, ncp= not.0) now longer gives erratic values for
	|x| < ~1e-12.  (PR#8874)

    o	\code{\linkS4class{.}} now works.

    o	ccf() aligns time series by ts.intersect() rather than
	ts.union() and so is less likely to need a non-default
	na.action.  (PR#8893)

    o	optim(method="CG") could return a value that did not
	correspond to $par for very badly behaved functions on which
	the second phase of the line search failed.  (PR#8786)

    o	print.ts() could fail on a corrupt time series: it now warns and
	does the best it can.
