    display: the display on which the graphics window will
             appear.  The default is to use the value in the
             user's environment variable `DISPLAY'.

      width: the width of the plotting window in inches.

     height: the height of the plotting window in inches.

         ps: the default pointsize to be used.

   printcmd: the command used to print a hardcopy.

      paper: the paper type for hardcopy, currently `"a4"' or
             `"letter"'.

   orientation: the orientation for hardcopy, one of `"por-
             trait"', `"landscape"', or `"flexible"'.

        `x11' starts a graphics device driver for the X Window
        System (version 11).  This should be done automagically
        at start up time and can only be done on machines that
        run X.

        `print.plot()' prints the plot using the `printcmd'
        command.  `save.plot("fig.ps")' saves an encapsulated
        postscript version of the plot in the file "fig.ps"
        (attempting to be pretty wysiwyg).  Both make use of
        the `paper' and `orientation' arguments.
