Hi Ivan,

Can you educate me a little bit on the use of barchart?

Unfortunately no... For this post I eventually used the barplot2() in the
gplots packages. I got bogged down trying to do it in lattice so I looked
for an alternative. It was quite straight forward which was nice and I was
able to get what I wanted quite quickly. Sorry I can't be of more help.
