Dear all,

I am looking for a method to draw multiple rectangles in different 
colors plus arrows between them (given a data matrix with the relevant 
coordinate and size information).

After looking around mainly on:
and the Rseek page
the Grid package seems one possible way to go.

Are there better suited packages for such graphs?

Thanks for a pointer
