Log Message:
Update R to 2.2.1

USER-VISIBLE CHANGES

    o   options("expressions") has been reduced to 1000: the limit
        of 5000 introduced in 2.1.0 was liable to give crashes from C
        stack overflow.

NEW FEATURES

    o   Use of 'pch' (e.g. in points) in the symbol font 5 is now
        interpreted in the single-byte encoding used by that font.
        Similarly, strwidth now recognizes that font 5 has a different
        encoding from that of the locale.  (These are likely to affect
        the answer only in MBCS locales such as UTF-8.)

    o   The URW font metrics have been updated to versions from late
        2002 which cover more glyphs, including Cyrillic.

    o   New postscript encodings for CP1250 (Windows East European),
        ISO Latin-7 (8859-13, Latvian, Lithuanian and Maori), Cyrillic
        (8859-5), KOI8-R, KOI8-U and CP1251.

    o   configure has more support for the Intel and Portland Group
        compilers on ix86 and x86_64 Linux.

    o   R CMD INSTALL will clean up if interrupted (e.g. by ctrl-C from
        the keyboard).

    o   There is now a comprehensive French translation of the messages,
        thanks to Philippe Grosjean.

DEPRECATED & DEFUNCT

    o   The undocumented use of atan() with two arguments is deprecated:
        instead use atan2() (as documented).

    o   The 'vfont' argument of axis() and mtext() is deprecated
        (it currently warns and does nothing).

    o   The function mauchley.test() is deprecated (was a misspelling)
        and replaced by mauchly.test()
