Dear R graphics experts,
Do you know of any way of plotting semi-transparent points in R ?
I face this problem any time I want to e.g. plot thousands of points
that belong to two or three classes which I color code.
With the default opaque colors, the plotting order matters and
basically the points I plot last completely dominate the picture. I
would much rather have the overlaying points mix in color..
Thanks a lot,
