One approach for this would be to place the legend to the right of the

2) adjust nrows so that the full width of the drawing device is used,
3) use layout() so that enough space is allocated beneath the graph for
4) draw legend
5) allow user to call plot, correctly drawing the plot in the remaining
I have taken a look at this, but I am confused by the different units
used by par(mar), legend(plot=F), and layout.
