        palette(value)

   AArrgguummeennttss::

      value: an optional character vector.

        This function is used to view or manipulate the color
        palette which is used when a `col=' has a numeric
        index.

        If `value' has length 1 it is taken to be the name of a
        built in color palette.  If `value' has length greater
        than 1 it is assumed to contain a description of the
        colors which are to make up the new palette (either by
        name or by RGB levels).

        If `value' is omitted or has length 0, no change is
        made the current palette.

        Currently, the only built-in palette is `"default"'.

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

        The palette which was in effect.  This is invisible
        unless the argument is omitted.

   SSeeee AAllssoo::

        `colors' for the vector of built-in ``named'' colors;
        `hsv', `gray', `rainbow', `terrain.colors',... to con-
        struct colors.

   EExxaammpplleess::

        palette()           # obtain the current palette
        palette(rainbow(6)) # six color rainbow
        palette("default")  # reset back to the default
