          x: the coordinates of points given as columns of a
             matrix.

     labels: the names of the variables.

      panel: the function which is used to plot the contents of
             each panel of the display.

        A matrix of scatterplots is produced.  The ijth scat-
        terplot contains `x[,i]' plotted against `x[,j]'.  The
        graphical parameters `pch' and `col' can be used to
        specify a vector of plotting symbols and colors to be
        used in the plots.
