I've rolled up R-2.2.0.tar.gz a short while ago. This version contains
several changes and additions, mostly incremental. See the full list
of changes below.

You can get it from

http://cran.r-project.org/src/base/R-2/R-2.2.0.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.

Here is the relevant bit of the NEWS file:


		CHANGES IN R VERSION 2.2.0


USER-VISIBLE CHANGES

    o	plot(<lm object>) uses a new default 'which = 5'
    	for the fourth panel when 'which' is not specified.

    o	The SVN revision number will appear after the date in the
	welcome message.  The date shown is now the date of the last
	change to the sources rather than the date the sources were
	prepared.

    o	is.null(expression()) now returns FALSE.  Only NULL gives TRUE
	in is.null().

    o	graphics::xy.coords, xyz.coords and n2mfrow have been moved to
	the grDevices name space (to be available for grid as well).

	graphics::boxplot.stats, contourLines, nclass.*, and chull
	have been moved to the grDevices name space.  The C code
	underlying chull() has been moved to package grDevices.

    o	split(x, f), split<-() and unsplit() now by default split by all
	levels of a factor f, even when some are empty.
	Use split(x, f, drop = TRUE) if you want the old behavior of
	dropping empty levels.	split() and split<-() are S3 generic
	functions with new arguments 'drop' and '...' and all methods now
	should have 'drop' and '...' arguments as well.

    o	The default for 'allowEscapes' in both read.table() and scan()
	has been changed to FALSE.

    o	The default for 'gcFirst' in system.time() is now TRUE.


NEW FEATURES

    o	.Platform has a new component 'path.sep', the separator used
	between paths in environment variables such as PATH and TEXINPUTS.

    o   anova.mlm() now handles the single-model case.

    o	Hexadecimal values are now allowed for as.numeric() and
	as.integer() on all platforms, and as integer constants in R code.

    o	attach() now prints an information message when objects are
	masked on the search path by or from a newly attached database.

    o	axis() now returns 'at' positions.

    o   axis() has a new argument 'hadj' to control horizontal
	adjustment of labels.

    o	axis.Date() and axis.POSIXct() now accept a 'labels' argument
	(contributed by Gavin Simpson).

    o	barplot() now has arguments 'log = ""' and 'add = FALSE'
	(as in barplot2() from package 'gplots').

    o	baseenv() has been added, to return the base environment.  This
    	is currently still NULL, but will change in a future release.

    o   boxplot() now responds to supplying 'yaxs' (via bxp()).
	(Wish of PR#8072.)

    o	capabilities() has a new component 'NLS'.

    o	cbind() and rbind() now react to 'deparse.level' = {0,1,2}
	(as in another system not unlike R).

    o	Experimental versions of cbind() and rbind() in methods package,
	based on new generic function cbind2(x,y) and rbind2().	 This will
	allow the equivalent of S4 methods for cbind() and rbind() ---
	currently only after an explicit activation call, see ?cbind2.

    o	New functions cdplot() and spineplot() for conditional density
        plots and spine plots or spinograms.  Spine plots are now used
        instead of bar plots for x-y scatterplots where y is a factor.

    o	checkDocFiles() in package 'tools' now checks for bad \usage
	lines (syntactically invalid R code).

    o   The nonparametric variants of cor.test() now behave better in
	the presence of ties. The "spearman" method uses the asymptotic
	approximation in that case, and the "kendall" method likewise,
	but adds a correction for ties (this is not necessary in the
	Spearman case).

    o	The X11 dataentry() now has support for X Input Methods
	(contributed by Ei-ji Nakama).

    o	density() is now an S3 generic where density.default() {former
	density()} has new argument 'weights' for specifying observation
	masses different than the default 1/N -- based on a suggestion and
	code from Adrian Baddeley.

    o	download.packages() now carries on if it encounters a download
	error (e.g. a repository with a corrupt index).

    o	dump() now skips missing objects with a warning rather than
	throw an error.

    o   Added "POSIXlt" methods for duplicated() and unique().

    o	Function encoded_text_to_latex() in package tools translates
	Latin 1,2,9 and UTF-8 encoded character vectors to LaTeX
	escape sequences where appropriate.

    o	encodeString() allows justify = "none" for consistency with
	format.default().  Some argument names have been lengthened
	for clarity.

    o	file(), fifo() and pipe() now (if possible) report a reason
        if they fail to open a connection.

    o	format.default() now has a 'width' argument, and 'justify' can
	now centre character strings.

	format.default() has new arguments 'na.encode' to control
	whether NA character strings are encoded (true by default),
	and 'scientific' to control the use of fixed/scientific
	notation for real/complex numbers.

	How format() works on a list is now documented, and uses
	arguments consistently with their usage on an atomic vector.

    o	format.info() now has a 'digits' argument, and is documented
	to work for all atomic vectors (it used to work for all but
	raw vectors.).

    o	New function glob2rx() for translating `wildcard' aka `globbing'
	to regular expressions.

    o	There is a new function gregexpr() which generalizes regexpr()
        to search for all matches in each of the input strings (not
        just the first match).

    o	[g]sub() now have a 'useBytes' argument like grep() and regexpr().

    o	[g]sub(perl = TRUE) support \L and \U in the replacement.

    o   iconv() has been moved from 'utils' to 'base'.

    o	identify()'s default method has additional arguments 'atpen'
	and 'tolerance' (following S).

    o	KalmanForecast() and KalmanLike() now have an optional argument
	fast=FALSE to prevent their arguments being modified.

    o	Exact p-values are available in ks.test() for the one-sided and
	two-sided one-sample Kolmogorov-Smirnov tests.

    o	labels() now has a method for "dist" objects (replacing that
	for names() which was withdrawn in 2.1.0).

    o	library() now explicitly checks for the existence of
	directories in 'lib.loc': this avoids some warning messages.

    o	loadNamespace(keep.source=) now applies only to that namespace
	and not others it might load to satisfy imports: this is now
	consistent with library().

    o	match.arg() has a new argument 'several.ok = FALSE'.

    o	max.col() has a new argument for non-random behavior in the
	case of ties.

    o   memory.profile() now uses the type names returned by typeof()
	and no longer has two unlabelled entries.

    o	methods() now warns if it appears to have been called on a
	non-generic function.

    o	The default mosaicplot() method by default draws grey boxes.

    o	nlminb(), similar to that in S-PLUS, added to package 'stats'.

    o	New algorithm "port" (the nl2sol algorithm available in the
	Port library on netlib) added to the nls() function in the
	'stats' package.

    o	object.size() now supports more types, including external
	pointers and weak references.

    o	options() now returns its result in alphabetical order, and is
	documented more comprehensively and accurately.  (Now all
	options used in base R are documented, including
	platform-specific ones.)

	Some options are now set in the package which makes use of
	them (grDevices, stats or utils) if not already set when the
	package is loaded.

    o	New option("OutDec") to set the decimal point for output conversions.

    o	New option("add.smooth") to add smoothers to a plot, currently
	only used by plot.lm().

    o	pie() has new optional arguments 'clockwise' and 'init.angle'.

    o	plot.lm() has two new plots (for 'which' = 5 or 6), plotting
	residuals or cook distances versus (transformed) leverages - unless
	these are constant.  Further, the new argument 'add.smooth' adds a
	loess smoother to the point plots by default, and 'qqline = TRUE'
	adds a qqline() to the normal plot.
	The default for 'sub.caption' has been improved for long calls.

    o	R.home() has been expanded to return the paths to components
	(which can as from this version be installed elsewhere).

    o   readbin() and writeBin() now support raw vectors as well as
	filenames and connections.

    o	read.dcf() can now read gzipped files.

    o	read.table() now passes 'allowEscapes' to scan().

    o	sample(x, size, prob, replace = TRUE) now uses a faster
	algorithm if there are many reasonably probable values.  (This
	does mean the results will be different from earlier versions
	of R.)  The speedup is modest unless 'x' is very large _and_
	'prob' is very diffuse so that thousands of distinct values
	will be generated with an appreciable frequency.

    o	scatter.smooth() now works a bit more like other plotting
	functions (e.g., accepts a data frame for argument 'x').
	Improvements suggested by Kevin Wright.

    o	signif() on complex numbers now rounds jointly to give the
	requested number of digits in the larger component, not
	independently for each component.

    o	New generic function simulate() in the 'stats' package with
	methods for some classes of fitted models.

    o	smooth.spline() has a new argument 'keep.data' which allows to
	provide residuals() and fitted() methods for smoothing splines.

    o	Attempting source(file, chdir=TRUE) with a URL or connection
	for 'file' now gives a warning and ignores 'chdir'.

    o	source() closes its input file after parsing it rather than
	after executing the commands, as used to happen prior to
	2.1.0.  (This is probably only significant on Windows where
	the file is locked for a much shorter time.)

    o	split(), split<-(), unsplit() now have a new argument 'drop = FALSE',
	by default not dropping empty levels; this is *not* back compatible.

    o	sprintf() now supports asterisk `*' width or precision
	specification (but not both) as well as `*1$' to `*99$'.  Also the
	handling of `%' as conversion specification terminator is now
	left to the system and doesn't affect following specifications.

    o	The plot method for stl() now allows the colour of the range
	bars to be set (default unchanged at "light gray").

    o	Added tclServiceMode() function to the tcltk package to allow
	updating to be suspended.

    o	terms.formula() no longer allows '.' in a formula unless there
	is a (non-empty) 'data' argument or 'allowDotAsName = TRUE' is
	supplied.  We have found several cases where 'data' had not
	been passed down to terms() and so '.' was interpreted as a
	single variable leading to incorrect results.

    o	New functions trans3d(), the 3D -> 2D utility from persp()'s
	example, and extendrange(), both in package 'grDevices'.

    o	TukeyHSD() now returns p-values adjusted for multiple comparisons
	(based on a patch contributed by Fernando Henrique Ferraz P. da Rosa).

    o	New functions URLencode() and URLdecode(), particularly for use
	with file:// URLs.  These are used by e.g. browse.env(),
	download.file(), download.packages() and various help() print
	methods.

    o	Functions utf8ToInt() and intToUtf8() to work with UTF-8
	encoded character strings (irrespective of locale or OS-level
	UTF-8 support).

    o	[dqp]wilcox and wilcox.test work better with one very large sample
	size and an extreme first argument.

    o	write() has a new argument 'sep'.

    o	write.csv[2] now also support row.names = FALSE.



    o	The specification of the substitutions done when processing
	Renviron files is more liberal: see ?Startup.  It now
	accepts forms like R_LIBS=${HOME}/Rlibrary:${WORKGRP}/R/lib .

    o	Added recommendation that packages have an overview man page
	<pkg>-package.Rd, and the promptPackage() function to create a
	skeleton version.

    o	Replacement indexing of a data frame by a logical matrix index
	containing NAs is allowed in a few more cases, in particular
	always when the replacement value has length one.

    o	Conversion of .Rd files to latex now handles encoding more
	comprehensively, including some support for UTF-8.

    o	The internal regex code has been upgraded to glibc-2.3.5.
	Apart from a number of bug fixes, this should be somewhat
	faster, especially in UTF-8 locales.

    o	PCRE has been updated to version 6.2.

    o	zlib has been updated to version 1.2.3.

    o	bzip2 has been updated to version 1.0.3.

    o	Complex arithmetic is now done by C99 complex types where
	supported.  This is likely to boost performance, but is
	subject to the accuracy with which it has been implemented.

    o	The printing of complex numbers has changed, handling numbers
	as a whole rather than in two parts.  So both real and
	imaginary parts are shown to the same accuracy, with the
	'digits' parameter referring to the accuracy of the larger
	component, and both components are shown in fixed or
	scientific notation (unless one is entirely zero when it is
	always shown in fixed notation).

    o	Error messages from .C() and .Fortran(), and from parsing errors,
	are now more informative.

    o	The date and date-time functions work better with dates more
	than 5000 years away from 1970-01-01 (by making dubious
	assumptions about the calendar in use).

    o	There is now a traditional Chinese translation, and a much more
	extensive Russian translation.


DEPRECATED & DEFUNCT

    o	Capability "IEEE754" is defunct.

    o	loadURL() is defunct: use load(url()).

    o	delay() is defunct: use delayedAssign() instead.

    o	The 'CRAN' argument to update.packages(), old.packages(),
	new.packages(), download.packages() and install.packages() is
	defunct in favour of 'repos'.

    o	write.table0() is deprecated in favour of the much faster
	write.table().

    o	format.char() is deprecated in favour of format.default().

    o	R_HOME/etc/Rprofile is no longer looked for if
	R_HOME/etc/Rprofile.site does not exist.  (This has been
	undocumented since R 1.4.0.)

    o	CRAN.packages() is deprecated in favour of available.packages().

    o	Rd.sty no longer processes pre-2.0.0 conversions containing \Link.

    o	The stubs for the defunct device GNOME/gnome have been removed.

    o	print.matrix() (which has been identical to print.default since
	R 1.7.0) has been removed.


INSTALLATION

    o	LDFLAGS now defaults to -L/usr/local/lib64 on most Linux
	64-bit OSes (but not ia64).  The use of lib/lib64 can be
	overridden by the new variable LIBnn.

    o	The default installation directory is now ${prefix}/${LIBnn}/R,
	/usr/local/lib64/R on most 64-bit Linux OSes and /usr/local/lib/R
	elsewhere.

    o	The places where the doc, include and share directory trees are
	installed can be specified independently: see the R-admin manual.

    o	We now test for wctrans_t, as apparently some broken OSes have
	wctrans but not wctrans_t (which is required by the relevant
	standards) .

    o	Any external BLAS found is now tested to see if the complex
	routine zdotu works correctly: this provides a compatibility
	test of compiler return conventions.

    o	Installation without NLS is now cleaner, and does not install
	any message catalogues.

    o	src/modules/lapack/dlamc.f is now compiled with -ffloat-store
	if f2c/gcc are used, as well as if g77 is used.

    o	All the Fortran code has been checked to be fully F77
	compliant so there are no longer any warnings from F95
	compilers such as gfortran.

    o	The (not-recommended) options --with-system-zlib,
	--with-system-bzlib and -with-system-pcre now have 'system' in
	the name.

    o	If a Java runtime environment is detected at configure time
	its library path is appended to LD_LIBRARY_PATH or equivalent.
	New Java-related variables JAVA_HOME (path to JRE/JDK), JAVA_PROG
	(path to Java interpreter), JAVA_LD_PATH (Java library path)
	and JAVA_LIBS (flags to link against JNI) are made available
	in Makeconf.

    o	Ei-ji Nakama was contributed a patch for FPU control with the
	Intel compilers on ix86 Linux.


MAC OS X INSTALLATION

    o	--with-blas="-framework vecLib" --with-lapack and
	--with-aqua are now the default configure options.

    o	The default framework version name was changed to not contain
	the patch level (i.e. it is now 2.2 instead of 2.2.0).  Also
	it can be overridden at configure time by setting FW_VERSION
	to the desired name.

    o	The Rmath stand-alone library is now correctly installed inside
	the R.framework if R was configured as a framework.  In
	addition, make install-Rmath-framework will install a
	stand-alone Rmath framework in /Library/Frameworks (unless
	overridden by RMATH_FRAMEWORK_DIR specifying full framework
	path and name including the .framework extension).


PACKAGE INSTALLATION

    o	The encoding for a packages' 00Index.html is chosen from the
	Encoding: field (if any) of the DESCRIPTION file and from the
	\encoding{} fields of any Rd files with non-ASCII titles.
	If there are conflicts, first-found wins with a warning.

    o	R_HOME/doc/html/packages.html is now remade by R not Perl code.
	This may result in small changes in layout and a change in
	encoding (to UTF-8 where supported).

    o	The return value of new.packages() is now updated for any
	packages which may be installed.

    o	available.packages() will read a compressed PACKAGES.gz file in
	preference to PACKAGES if available on the repository: this
	will reduce considerably the download time on a dialup connection.

	The downloaded information about a repository is cached for the
	current R session.

    o	The information about library trees found by
	installed.packages() is cached for the current session, and
	updated only if the modification date of the top-level
	directory has been changed.

    o	A data index is now installed for a package with a 'data' dir
	but no 'man' dir (even though it will have undocumented data objects).

    o	contrib.url path for type="mac.binary" has changed from
	bin/macosx/<version> to	bin/macosx/<arch>/contrib/<version>
	where <arch> corresponds to R.version$arch


UTILITIES

    o	checkFF() used by R CMD check has since R 2.0.0 not reported
	missing PACKAGE arguments when testing installed packages with
	namespaces.  It now

	- treats installed and source packages in the same way.

	- reports missing arguments unless they are in a function in
	  the namespace with a useDynLib declaration (as the
	  appropriate DLL for such calls can be searched for).

    o	Rd2dvi sets the encoding(s) used appropriately.	 If UTF-8
	encoding is used, latex >= 2003/12/01 is required.

    o	codoc() allows help files named pkg_name-defunct.Rd to have
	undocumented arguments (and not just base-defunct.Rd).


C-LEVEL FACILITIES

    o	C function massdist() {called from density()} has new argument
	'xmass' (= weights).

    o	Raw vectors passed to .C() are now passed as unsigned char *
	rather than as SEXPs.  (Wish of Keith Frost, PR#7853)

    o	The search for symbols in a .C/.Call/... call without a
	package argument now searches for an enclosing namespace and
	so finds functions defined within functions in a namespace.

    o	R_max_col() has new (5th) argument '*ties_meth' allowing
	non-random behavior in the case of ties.

    o	The header files have been rationalized: the BLAS routine
	LSAME is now declared in BLAS.h not Linpack.h, Applic.h no
	longer duplicates routines from Linpack.h, and Applic.h is
	divided into API and non-API sections.

    o   memory.c has been instrumented so that Valgrind can track R's
        internal memory management.  To use this, configure using
               --with-valgrind-instrumentation=level
        where level is 1 or 2.  Both levels will find more bugs with
        gctorture(TRUE).  Level 2 makes Valgrind run extremely slowly.

    o	Some support for raw vectors has been added to Rdefines.h.

    o	R_BaseEnv has been added, to refer to the base environment.
    	This is currently equal to R_NilValue, but it will change in
    	a future release.


BUG FIXES

    o	%/% has been adjusted to make x == (x %% y) + y * ( x %/% y )
	more likely in cases when extended-precision registers were
	interfering.

    o	Operations on POSIXct objects (such as seq(), max() and
	subsetting) try harder to preserve time zones and warn if
	inconsistent time zones are used.

    o	as.function.default() no longer asks for a bug report when
	given an invalid body. (PR#1880, PR#7535, PR#7702)

    o	Hershey fonts and grid output (and therefore lattice output)
	now rescale correctly in fit-to-window resizing on a Windows
	graphics device.  Line widths also scale now.

    o	Plotmath has more support for multibyte characters (contributed
	by Ei-ji Nakama).

    o	The X11() device now hints the window manager so that decorations
	appear reliably under e.g. the GNOME WM	 (contributed
	by Ei-ji Nakama).

    o	Subsetting a matrix or an array as a vector used to attempt to
	use the row names to name the result, even though the
	array might be longer than the row names.  Now this is only
	done for 1D arrays when it is done in all cases, even matrix
	indexing.  (Tidies up after the fix to PR#937.)

    o	Constants in mathlib are declared 'const static double' to
	avoid performance issues with the Intel Itanium compiler.

    o	The parser checks the format of numeric constants more
	thoroughly so for example '123E-' is no longer valid.

    o	contourLines() no longer requires an open device (used to
	start a device unnecessarily).	Fix suggested by Barry Rowlingson.

    o	capabilities() used partial matching but was not documented
	to: it no longer does so.

    o	kernel(1,0) printed wrongly;  kernel(<name-string>, *) now returns
	a named kernel in all cases; plot(kernel(.),..) is more flexible.

    o	qgamma(1,s) didn't give +Inf for some s.

    o	installed.packages() and download.packages() now always
	return a matrix as documented, possibly with 0 rows (rather than
	a 0-length character vector or NULL).

    o	Arithmetic operations on data frames no longer coerce the
	names to syntatically valid names.

    o	Units are now properly recycled in grid layouts
	when 'widths' or 'heights' are shorter than the number of
	columns or rows (PR#8014).

    o	DF <- data.frame(A=1:2, B=3:4); DF[1, 1:3] <- NULL gave a wrong
	error message.

    o	spline()/spinefun()'s C code had a memory access buglet which
	never lead to incorrect results.  (PR#8030)

    o	sum() was promoting logical arguments to double not integer
	(as min() and other members of its group do).

    o   loess() had a bug causing it to occasionally miscalculate
        standard errors (PR#7956).  Reported by Benjamin Tyner, fixed
        by Berwin Turlach.

    o	library(keep.source=) was ignored if the package had a
	namespace (the setting of options("keep.source.pkgs") was
	always used).

    o	hist.POSIXct() and hist.Date() now respect par("xaxt").

    o	The 'vfont' argument was not supported correctly in title(),
	mtext(), and axis().  The 'vfont' argument is superseded by
	the par(family=) approach introduced in 2.0.0.  This bug-fix
	just updates the warning messages and documentation to
	properly reflect the new order of things.

    o	The C-level function PrintGenericVector could overflow if
	asked to print a length-1 character vector of several thousand
	characters.  This could happen when printing a list matrix,
	and was fatal up to 2.1.1 and silently truncated in 2.1.1 patched.

    o	What happened for proc.time() and system.time() on
	(Unix-alike) systems which do not support timing was
	incorrectly documented.  (They both exist but throw an error.)
	Further, systen.time() would give an error in its on.exit
	expression.

    o	weighted.residuals() now does sensible things for glm() fits:
	in particular it now agrees with an lm() fit for a Gaussian glm()
	fit.  (PR#7961).

    o   The 'lm' and 'glm' methods for add1() took the weights and
	offset from the original fit, and so gave errors in the
	(dubious) usage where the upper scope resulted in a smaller
	number of cases to fit (e.g. by omitting missing values in new
	variables).  (PR#8049)

    o	demo() had a 'device' argument that did nothing (although it
	was documented to): it has been removed.

    o	Setting new levels on a factor dropped all existing
	attributes, including class "ordered".

    o	format.default(justify="none") now by default converts NA
	character strings, as the other values always did.

    o	format.info() often gave a different field width from format()
	for character vectors (e.g. including missing values or
	non-printable characters).

    o	axis() now ensures that if 'labels' are supplied as character
	strings or expressions then 'at' is also supplied (since the
	calculated value for 'at' can change under resizing).

    o	Defining S4 methods for "[" had resulted in changed behavior of S3
	dispatch in a very rare case which no longer happens.

    o	Fixed segfault when PostScript font loading fails, e.g., when
	R is unable to find afm files (reported by Ivo Welch).

    o	R CMD BATCH <file> now also works when <file> does not end in a
	newline on Unix-alike platforms.

    o   terms.formula() got confused if the 'data' argument was a list with
	non-syntactic names.

    o	prompt() and hence package.skeleton() now produce *.Rd files that
	give no errors (but warnings) when not edited, much more often.

    o	promptClass() and promptMethods() now also escape "%" e.g. in '%*%'
	and the latter gives a message about the file written.

    o	wilcox.test() now warns when conf.level is set higher than
	achievable, preventing errors (PR#3666) and incorrect answers
	with extremely small sample sizes.

    o	The default (protection pointer) stack size (the default for
	'--max-ppsize') has been increased from 10000 to 50000 in order to
	match the increased default options("expressions") (in R 2.1.0).

    o	The R front-end was expecting --gui=tk not Tk as documented,
	and rejecting --gui=X11.

    o	Rdconv -t latex protected only the first << and >> in a chunk
	against conversion to guillemets.

    o	callNextMethod() and callGeneric() have fixes related to
	handling arguments.

    o	ls.diag() now works for fits with missing data. (PR#8139)

    o	window.default() had an incorrect tolerance and so sometimes
	created too short a series if 'start' or 'end' were zero.

    o   Some (fairly pointless) cases of reshape left a
        temporary id variable in the result (PR#8152)

    o	R CMD build used 'tar xhf' which is invalid on FreeBSD systems
	(and followed tar chf, so there could be no symbolic links in
	the tarball).

    o	Subassignment of length zero vectors to NULL gave garbage
    	answers. (PR#8157)

    o	Automatic coercion of raw vectors to lists was missing, so for a
	list (or data frame) z, z[["a"]] <- raw_vector did not work
	and now does.  This also affected DF$a <- raw_vector for a
	data frame DF.

    o	The internal code for commandArgs() was missing PROTECTs.

    o	The width for strwrap() was used as one less than specified.

    o	R CMD INSTALL was not cleaning up after an unsuccessful
	install of a non-bundle which was not already installed.
