[R] graphs superimposed on pictures?

[Robert Biddle]

Hi:

I am doing some work that involves plotting points of interest
superimposed on photographs and maps. I can produce the plots fine in R, but so far
I have had to do the superimposition externally, which makes it tedious to do exploratory work.
I have looked to see if there is some capability to put a background picture on a plot window,
but I have not found anything.
Advice, anyone?

Cheers
