        In R, the startup mechanism is as follows.  R first
        searches for the site-wide startup profile unless the
        command line option `--no-site-file' was given.  The
        name of this file is taken from the value of the `RPRO-
        FILE' environment variable.  If that variable is unset,
        the default is `$RHOME/etc/Rprofile'.

        Then, unless `--no-init-file' was given, R searches for
        a file called `.Rprofile' in the current directory or
        in the user's home directory (in that order) and
        sources it.

        It also loads a saved image from `.RData' in case there
        is one (unless `--no-restore' was specified).

        Finally, if a function `.First' exists, it is executed
        as `.First()'.

        The functions `.First' and `.Last' can be defined in
        the appropriate startup profiles or reside in `.RData'.

   SSeeee AAllssoo::

        `.Last' for final actions before termination.
