[R] Coloring spaces between lines in xyplot

  I wish to create a stacked line graph in xyplot, adding color to the 
spaces between the lines. For example, the code below creates a plot 
with two lines extending across it, and I want to color the rhomboid 
that is between the upper and lower line, and between the lower line and 
the bottom of the frame.
Suggestions appreciated

I think polygon()  will do what you want.
