This seems like a natural fit for ggplot2 graphics, but I'm not aware of shading as a widely implemented graphical element: this might have some useful information -- http://had.co.nz/ggplot2/geom_histogram.html
Can you find an example of "shading" in R? (perhaps in the R Graphics Gallery) If you look at example(barplot) there's an example of how to use different line patterns, but I don't find it particularly clear. The grouping techniques seem much clearer to me.
