Usage: Rcmd $name [options] pkgs

Install the add-on packages specified by pkgs into the default R library
tree ($R_HOME/library) or the tree specified via \`--library'.  The

the package (bundle) sources, or to gzipped package \`tar' archives.

Options:
  -c, --clean       remove all files created during installation
  -d, --debug       [x] turn on shell and build-help debugging
  -h, --help        print short help message and exit
  -l, --library=LIB install packages to library tree LIB
      --docs=TYPE   type(s) of documentation to build and install
      --use-zip-data    collect data files in zip archive
      --use-zip-help    collect help and examples into zip archives
      --use-zip     combine \`--use-zip-data\' and \`--use-zip-help\'
  -v, --version     print version info and exit

TYPE can be "none" or "normal" or "chm" (the default) or "winhlp" or "all"
