Hi Simon, Thanks for the answer and the fix for the tilde. I did not realize it was up to you, I thought if R understood tilde, everything else having to do with R would. I was wrong.
As for the res question, actually increasing the size of the quartz window and controlling pointsize accordingly has proven a good enough solution. Certainly it is much easier than to take a quartz plot and try to imitate it in all details using the png device.
