R-1.6.1 is released

[Peter Dalgaard BSA]

I've rolled up R-1.6.1.tgz a short while ago. This is a minor upgrade,
fixing an assortment of minor bugs, and one major one: 1.6.0
introduced a memory leak in deparsing, causing much trouble for people
running simulations.

You can get it from the developer site at

http://cvs.r-project.org/pub/CRAN/src/base/R-1.6.1.tgz

or wait for it to be mirrored at a CRAN site near you. Binaries for
various platforms will appear in due course.
 
There is also a version split for floppies, but due to the inclusion
of recommended packages as binary .tar.gz files, I'm no longer
providing a patch file.


        For the R Core Team,

        Peter D.


Here's the relevant part of the NEWS file:


                CHANGES IN R VERSION 1.6.1


NEW FEATURES

    o   Added a few "trivial and obviously missing" functions to tcltk:
        tkchooseDirectory, tkpopup, tkdialog, tkread

    o   barplot() has a new argument `axis.lty', which if set to 1
        allows the pre-1.6.0 behaviour of plotting the axis and tick
        marks for the categorical axis.  (This was apparently not
        intentional, but axis() used to ignore lty=0.)
        The argument `border' is no longer ".NotYetUsed".


BUG FIXES

    o   hist(<datetime>, cex.axis = f)  now works for x-axis too.

    o   prompt() gave wrong \usage{.} for long argument default expressions.

    o   summary(x) gives more information when `x' is a logical
        (or a data frame with a logical column which is now quite customary).

    o   seq.POSIXt(from, to, length.out= . ) could give too long results

    o   summaryRprof() was counting nested calls to the same function
        twice.

    o   Printing of objects of mode "expression" did strange things if
        there were "%" characters in the deparsed expression (PR#2120).

    o   as.matrix.data.frame converted missings to "NA" not character NA.
        (PR#2130)

    o   spec.pgram() was only interpolating zero freq for one series. (PR#2123)

    o   help(randu) had % unescaped in the example. (PR#2141)

    o   Making html links would fail if packages-head.html was not
        writeable. (PR#2133)

    o   Sweave.sty was not installed to $R_HOME/share/texmf when
        builddir != srcdir. On Windows backslashes in latex paths have
        to be replaced by slashes.

    o   A memory leak in deparsing was introduced when eliminating
        static variables (thanks to Achim Zeileis for spotting this).
        A similar problem in loading workspaces has been corrected.

    o   TclInterface.Rd incorrectly used \synopsis for \usage so that
        the usage section wasn't output.

    o   Readline stack off-by-one error. (PR#2165)

    o   R_ExpandFileName had a memory leak in the case libreadline was
        used under Unix-alikes.

    o   sys.save.image() now closes all connections so it will work even
        if the connection list has become full.

    o   loess() had an unstated limit of four predictors: this is now
        documented and enforced.

    o   ${R_HOME}/etc/Renviron.site is now not read if R_ENVIRON is
        set, as documented.  Previously it was read unless R_ENVIRON
        pointed to an actual file.

    o   Startup.Rd described the proceesing under Unix-alikes but
        incorrectly implied it happened that way on the Windows and
        MacOS ports.  Neither use Renviron.site, for example.

    o   besselK(x,*) now returns 0 instead of Inf for large x. (PR#2179)

    o   The Tcl console code didn't work with Tcl/TK 8.0, and has been
        #ifdef'd out.  (PR#2090)

    o   format.AsIs() was not handling matrices.

    o   sd() was not passing na.rm to var() for matrices and data frames.

    o   dist() {mva} silently treated +/-Inf as NA.

    o   setwd() now returns NULL invisibly.

    o   basename() and dirname() did not check the length of their
        input and ignored elements after the first.  This affected
        undoc {tools}.

    o   If A had dimnames, eigen(A) had inappropriate dimnames. (PR#2116)

    o   as.POSIXct.dates had a sign error for the origin (PR#2222)

    o   The claim that pie charts should be avoiden (in pie.Rd) is now
        supported by a quote from Cleveland (1985).

    o   The vsnprintf() functions supplied for systems that don't
        supply their own had a bug in the output of fractional parts,
        corrupting data if using save() with ascii=TRUE. (PR#2144)

    o   pretty() values close to 0 in some cases which are now 0 (PR#1032
        and D.Brahm's mails).


BUILD ISSUES

    o   Toplevel Makefile was missing dependency of "docs" on "R" (causing
        parallel makes to go wrong)

    o   When building with recommended packages those were installed
        into the first path in R_LIBS, if the environment variable was
        present.
