The reason for my question is that a pdf-publication site is asking for a
total size of document
less than 2MB.   My R-graphs are simple plots of many points. I migth try to
tell the same story by
using fewer points.  An old (10 years +) Splus gave a particular graph 68k
wheras the corresponding
R was something like 1MB+.  My latex documents therefore become huge.  The
explanation I got was
that Splus used some kind of compression optimization which was absent in R.

Perhaps it is better to try to generate other form of the graph than ps or
to generate the
graph using a subsample of the points.
