        `data' loads a data set or lists (via `show.data') the
        available data sets.

        data(..., list = character(0), package = c(.packages(),.Autoloaded),
             lib.loc = .lib.loc)

        ...: a sequence of `name's or character strings

       list: a character vector

    package: a name or character vector giving the packages to
             look into for data sets.  By default, all packages
             in the search path are used.

    lib.loc: a character vector of directory names of R
             libraries.  Defaults to all libraries currently
             known.

   DDeettaaiillss::

        Currently, four formats of data files are supported:

           * files ending `".RData"' or `".rda"' are
             `load()ed'.

      * files ending `".R"' or `".r"' are `source()d' in, with
        the R working directory changed temporarily to the
        directory containing the respective file.

      * files ending `".tab"' or `".txt"' are read using
        `read.table(..., header = TRUE)', and hence result in a
        `data.frame'.

      * files ending `".csv"' are read using `read.table(...,
        header = TRUE, sep=";")', and also result in a
        `data.frame'.

   VVaalluuee::

        A character vector of all data sets specified, an empty
        character vector if none were specified.

        `help' for obtaining documentation on data sets.

        data()                       # list all available data sets
        data(package = base)         # list the data sets in the base package
        data(USArrests, "VADeaths")  # load the data sets `USArrests and `VADeaths'
        help(USArrests)              # give information on data set `USArrests'
