[R] using barchart in lattice package and conditioning

I have the data structure below and I'm attempting to send it into barchart using the R code below it. I don't get an error but I don't get any output either. Deepyan's new Lattice book is amazing and there are some examples sort of similar to what i'm doing but I couldn't see a way of using the formula interface to condition on what I wanted to condition on so I decided to use split instead. I'm not sure if that's where my problem lies but if anyone has experience in using the barchart function in the lattice package and could take a look at what I'm trying to do,
it would really be appreciated. thanks.

p.s: my data set is already tallied by proportion so i don't need to use prop.table and i also have other additional columns in my data set. these two issues are complicating matters for me also. i'm a lattice newbie.
