I don't know that I can offer immediate help, but Paul Murrell and
I have nearly finished a complete rewrite of the graphics system which
should help.  The save.plot() and print.plot() commands were just
an interim solution and now we do something better.

This stuff will be in 0.62, which doesn't have a release date yet,
but I hope it will be pretty soon.

Quick Summary:

You start device drivers as a present:

	x11()

but you can have several graphics windows on screen at one time.
When you have an an on-screen picture you like, you can say

	dev.print(file="fig3.eps", height=4, width=5)

(any arguments to "postscript" are acceptable to dev.print).

It will also be possible to resize on-screen graphics windows and have
their contents redrawn to match the new size.  This is not just a
rescaling of the window contents as in Splus, but a complete redrawing
of the picture.
