R help - Dec 2009 - Positioning plots on top of each other (aligment & borders)

Hello,

I want to place two plots on top of each other. However, the problem
is that I can't figure out a simple way to align them correctly. Is
there a way to specify this?
Since the data is bunch of coordinates and the second layer is an
outline of a map (a .ps file I import using the grImport package), I
suppose one option would be to specify a set of "artificial"
coordinates that make up the very corners of that plot, and then have
the second layer will this same space. Any ideas how to do this?

Look at the subplot function in the TeachingDemos package, it may do what you
want.

Hi John,
I may be mistaken, but wouldn't it be easier to overlay your points on a 
map generated by the maps package? Your user units would then correspond 
to your coordinates.
