Most attachments are automatically stripped from r-help so we cannot see
your results. You may be able to get what you want with pyramid.plot in
package plotrix by changing the default values (it is designed for
population pyramids) or you may be able to get there using the layout()
function in base graphics before your plotting commands. Alternatively you
can set up a plot and then use the polygon() function to place the
rectangles where you want them.
