[R] changing pen mode [or adjusting for overlapping points?]

[Don Armstrong]

I'm ploting a rather large number of points [~24,000] in two series
with slightly different distributions.

I would like to be able to effectively see where the two distributions
overlap by setting the pen mode (or it's equivalent) to allow the
overlapping portion to show up as a different color (or different
shade).

Unfortunatly, I couldn't find an option in par or postscript that
looks like it would be of use.

Ideas or suggestions?
