See the source code for nber.xy and nberShade.ggplot in the "tis" 
package by Jeff Hallman. They both do what you want.

I'm working on something similar. Besides drawing the bands, my version 
will also vary heights optionally (rather than have bands stretching the 
entire height of the graph) and use ggplot2.
