[R] R 2.9.1 is released

[Peter Dalgaard]

I've rolled up R-2.9.1.tar.gz a few hours ago.

This is a maintenance release and fixes a number of mostly minor issues.

See the full list of changes below.

You can get it from

http://cran.r-project.org/src/base/R-2/R-2.9.1.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.

        For the R Core Team

Here is the relevant part of the NEWS file:

                CHANGES IN R VERSION 2.9.1

NEW FEATURES

    o   New function anyDuplicated(x) returns 0 (= FALSE) or the index
        of the first duplicated entry of x.

    o   matplot(), matlines() and matpoints() now also obey a 'lend'
        argument, determining line end styles. (Wish of PR#13619).

    o   bw.SJ(), bw.bcv() and bw.ucv() now gain an optional 'tol'
        argument allowing more accurate estimates.

    o   new.packages() no longer regards packages with the same name
        as a member of an installed bundle as 'new' (this is now
        consistent with the dependency checks in install.packages()).

        It no longer reports on partially installed bundles (since
        members can be updated individually if a bundle is unbundled).

    o   old.packages() and hence updates.packages() will look for
        updates to members of package bundles before updates to the
        whole bundle: this allow bundles to be split and installations
        updated.

    o   nlminb() gives better non-convergence messages in some cases.

    o   S3 method dispatch will support S4 class inheritance for S3
        methods, for primitives and via UseMethod(), if the argument
        S3methods=TRUE is given to setClass().  S4 method dispatch
        will use S3 per-object inheritance if S3Class() is set on the
        object.  See ?Methods and the paper referenced there.

    o   R CMD INSTALL is more tolerant of (malformed) packages with a
        'man' directory but no validly named .Rd files.

    o   R CMD check now reports where options are used that cause some
        of the checks to be skipped.

    o   RSiteSearch has been updated to be consistent with the new
        layout of the search site itself, which now includes separate
        options for vignettes, views, and r-sig-mixed-models, as well
        as changed names for r-help. (Contributed by Jonathan Baron.)

    o   That R CMD check makes use of a
        <pkg>/tests/Examples/<pkg>-Ex.Rout.save file as a reference
        result is now documented in 'Writing R Extensions'.

DEPRECATED & DEFUNCT

    o   print.atomic() (defunct since 1.9.0) has been removed since it
        caused confusion for an S4 class union "atomic".

    o   png(type="cairo1") is deprecated -- it was only needed for
        platforms with 1.0 <= cairo < 1.2.

BUG FIXES

    o   The ... argument was not handled properly when ... was found
        in the enclosure of the current function, rather than in the
        function header itself.  (This caused integrate() to fail in
        certain cases.)

    o   col2rgb("#00000080", TRUE) would return the background colour.
        (Reported by Hadley Wickham.)

    o   interaction() now ensures that the levels of the result are unique.

    o   packageDescription() and hence sessionInfo() now report the correct
        package version also for a non-attached loaded namespace of
        a version different from the default lib.loc.

    o   smoothScatter() now also works when e.g. xlim[2] < xlim[1].

    o   Invalid use of sprintf() such as sprintf("%S%") now give an error
        instead of a segmentation fault, as do very unusual cases such as
        sprintf("%s", tryCatch(stop(), error=identity)).  (It was
        always documented that misuse could crash R in
        platform-dependent ways.)

    o   parse_Rd() would mishandle braces when they occurred at
        the start of a line within an R string in an Rd file (reported
        by Alex Couture-Beil) or when they occurred in an R comment
        (reported by Mark Bravington).

    o   readNEWS() missed version numbers with more than one digit.

    o   building R --without-x no longer fails (PR#13665)

    o   printCoefmat(cbind(0,1)) now works too (PR#13677)

    o   bw.SJ(c(1:99, 1e6)) now works too.

    o   Rd2txt() could not handle empty descriptions of items in an Rd
        file (reported by Mark Bravington), and did not wrap long lists
        of arguments if they were given in a single item.

    o   stars() would do a partial plot when called with plot = FALSE;
        it now consistently returns the locations of the stars.

    o   Rd2latex() could not handle empty sections.

    o   old.packages() and hence update.packages() would fail on a
        repository which contained only one package but with multiple
        versions of that package.

    o   as.character.Rd() added extra braces when displaying two-argument
        macros.  (Report and fix by Manuel Eugster.)

    o   unsplit() was misbehaving in the case of single-column data
        frames. (Reported by Will Gray.)

    o   as(I(1), "vector") and similar coercions from objects of
        "unregistered" S3 classes now work.

    o   srcref records produced by parse() and parse_Rd() did not record
        the encoding of the source file.  (Reported by Romain Francois.)

    o   The X11 version of View() was misbehaving in MBCS locales, and
        PgUp/PgDn now behave better, thanks to a patch from Ei-ji Nakama.

    o   R CMD check looked at the environment variable PDFLATEX, but
        as from R 2.8.1 R CMD Rd2dvi used R_PDFLATEXCMD in
        preference, and that was set by R CMD (and not PDFLATEX).  Now
        R CMD check looks at R_PDFLATEXCMD.

    o   sprintf() now signals an error when the result of single format
        specification would be longer than the limit (8192 bytes); it would
        return "somewhat random" results or segfault previously. (PR#13667)
        Further, arguments of type "language" or "symbol" are no longer
        allowed, as these, e.g., sprintf("%s", quote(list())), typically
        lead to unexpected results or hard to understand error messages.

    o   The new (in 2.9.0) 'stringsAsFactors' argument to expand.grid()
        was not working: it now does work but has default TRUE for
        backwards compatibility.

    o   tcrossprod(<1d-array>, <matrix>) now does work when the arguments
        are of compatible dimensions.

    o   qbinom() now is accurate also in (large size, small prob)
        cases.  (PR#13711)

    o   The calculation of the Spearman p-value in cor.test() is
        slightly more accurate in some cases.  (PR#13574)

    o   The digamma(), trigamma() and psigamma() functions could be
        inaccurate for values of x around 1e-15 due to cancellation.
        (PR#13714).

    o   median.default() was altered in 2.8.1 to use sum() rather
        than mean(), although it was still documented to use mean().
        This caused problems for POSIXt objects, for which mean() but
        not sum() makes sense, so the change has been reverted.

    o   Assigning an extra 0-length column to a data frame by
        DF$foo <- value gave a corrupt data frame rather than failing.
        (PR#13724)  This also happened for DF[["foo"]] <- value.

    o   R CMD INSTALL no longer gives a spurious warning about old R
        versions ignoring multiple dependencies, if the conditions are
        known to be satisfied.

    o   The test for setting dim() allowed a value with two or more
        NAs to be set on a 0-length object.  (PR#13729)  Also, it
        allowed an even number of negative values.

    o   xtfrm(), rank(), sort() and order() did not always make use of
        custom comparison methods specific to the class of elements
        being sorted.

    o   Increase NAMED value on 'seq' value in for() loop so loop code
        cannot modify 'seq' value.

    o   Prevent rectangles of size < 0.5 pixel from disappearing in
        Quartz when using rastered backend.  (PR#13744)

    o   Printing _NA_complex_ had a low-level thinko; patch thanks to
        Bill Dunlap.

    o   CP1257 encoding for postscript/PDF has been corrected.  (PR#13736)

    o   aov() with an error term was evaluating the ... arguments in
        2.9.0 whilst checking their names, so could fail by evaluating
        them in the wrong place.  (PR#13733)

    o   The print() method for arima() failed if all coefs were fixed.

    o   R CMD INSTALL --no-latex was not implemented in 2.9.0 (only).

    o   Added a needed PROTECT call in RunFinalizers to handle cases where
        the routine is called recursively from a GC in a finalizer.

    o   Constructing error messages about unused arguments in calls to
        closures no longer evaluates the arguments.

    o   qr(x, LAPACK=TRUE) did not coerce integer x to numeric.

    o   qr.coef() misbehaved in the LAPACK case with a matrix RHS, so
        that solve(qr(x, LAPACK=TRUE)) gave wrong results. (Found by
        Avraham Adler, PR#13762 by Ravi Varadhan.)
