A bar graph including both stacked and grouped bars will put lots of pretty colors on the page and probably be eyecatching, but is unlikely to be the most effective way to convey the actual meaning of the data. I would recommend that you explore other possibilities for doing the plot. A dot plot may give you what you want, see the dotchart2 function in the Hmisc package or the dotplot function in the lattice package.
