[R-sig-Geo] combining different plot types

[Christoph Mülligann]

Hello list(),

I'd like to combine different kinds of plots. I know how to do that with 
print() for trellis objects and for ordinary plots with par() / 
layout(). However a combination of both object types (well, 
unfortunately ordinary plots appear to be not even objects) doesn't work 
with neither one of those functions. If one of you had a solution for 
this, that would save my day.

Best,

Christoph
