[R] Managing size of plots with many points

What is available to limit obvious overplotting, e.g. with a million
points? My primary motivation is to produce plots from R and S-Plus
that occupy minimal hard drive space without sacrificing visual clarity.
(I've crashed MicroSoft PowerPoint by including plots that are too big.)
Right now, I can think of three different scenarios:
1. Monotonic applications such as a normal probability plot.
2. Lines (or connected dots).
3. General scatterplots.
Several approaches have been suggested, and I've implemented an ugly
algorithm. However, I believe something better should be available, but
I don't even know what words to use in a search.
