Update to 2.14.2

CHANGES IN R VERSION 2.14.2:

  NEW FEATURES:

    o The internal untar() (as used by default by R CMD INSTALL) now
      knows about some pax headers which bsdtar (e.g., the default tar
      for Mac OS >= 10.6) can incorrectly include in tar files, and
      will skip them with a warning.

    o Function compactPDF() in package tools now takes the default for
      argument gs_quality from environment variable GS_QUALITY: there
      is a new value "none", the ultimate default, which prevents
      GhostScript being used in preference to qpdf just because
      environment variable R_GSCMD is set.  If R_GSCMD is unset or set
      to "", the function will try to find a suitable GhostScript
      executable.

    o For consistency with the logLik() method, nobs() for "nls" files
      now excludes observations with zero weight.  (Reported by Berwin
      Turlach.)

  UTILITIES:

    o R CMD check now reports by default on licenses not according to
      the description in 'Writing R Extensions'.

    o R CMD check has a new option --as-cran to turn on most of the
      customizations that CRAN uses for its incoming checks.

  PACKAGE INSTALLATION:

    o R CMD INSTALL will now no longer install certain file types from
      inst/doc: these are almost certainly mistakes and for some
      packages are wasting a lot of space.

CHANGES IN R VERSION 2.14.1:

  NEW FEATURES:

    o parallel::detectCores() is now able to find the number of
      physical cores (rather than CPUs) on Sparc Solaris.

      It can also do so on most versions of Windows; however the
      default remains detectCores(logical = TRUE) on that platform.

    o Reference classes now keep a record of which fields are locked.
      $lock() with no arguments returns the names of the locked fields.

    o HoltWinters() reports a warning rather than an error for some
      optimization failures (where the answer might be a reasonable
      one).

    o tools::dependsOnPkg() now accepts the shorthand dependencies =
      "all".

    o parallel::clusterExport() now allows specification of an
      environment from which to export.

    o The quartz() device now does tilde expansion on its file
      argument.

    o Option print in Sweave's RweaveLatex() driver now emulates
      auto-printing rather than printing (which can differ for an S4
      object by calling show() rather than print()).

    o filled.contour() now accepts infinite values: previously it might
      have generated invalid graphics files (e.g. containing NaN
      values).
