[R] saving intermediate graphics

[Charles Annis, P.E.]

Greetings, R-friends:

I'm using R 2.3.1 on a DELL box with 2 gig, running WindowsXP Pro.

I am making what is admittedly a very busy plot composed of qq plots with
superimposed density() plots.  I need to show everything and the result is
messy, but informative.

If I produce the basic qq plot, and then add incrementally to it, saving the
graphic at each step, the sequence does make the entire exercise
understandable.  (Honest!)

I can do this easily by clicking on the plot and saving it to PowerPoint as
a metafile.

I would like to automate the process.  I know how to produce win.metafiles,
but closing the file with dev.off() to produce the first graphic means that
I can't add to that and produce the subsequent graphic and file.

Is there a way to do this without generating the entire plot from the
beginning for each graphic?

Thanks
