[R-sig-Geo] Feature space plotting

Hi - Before I embark to develop a script to create feature space plots 
of two image bands I was wondering if anyone was aware of a package that 
provides this capability. I would like to be able to plot pixel values 
from one image band on the X-axis and pixel values from the another band 
on the Y-axis and show different frequencies of occurrence in the 
different plot bins with different colors. I would then overlay training 
data on the graph to see how well it is distributed in the 2-band 
feature space.

This should be pretty easy to implement but I thought I'd check first.
