[R] Aha, it was a problem in gv, not R!

Yesterday I asked about saved ps files not being the same as screen
appearance. Today I've just discovered the problem is in gv, the ps
viewer, rather than R, because I can print those R-outputted ps files on
the printer and they look fine. In addition, I downloaded the Gnome
viewer "ggv" and it shows the lines as they ought to be.
I'm still trying to configure this output the way I need it. If
somebody has a relatively full-featured example of a program with a
graph with lots of separate things on it, I could probably figure what I
need from that. I keep getting stuck on all these little details, like
trying to set the legend for the separate lines or controlling the paper
size of the postscript output.
Thanks in advance.
