I am using ggplot2 at the moment and I must say it is definitely better then ggplot - good work.

My problem is that I am using facet_grid() in the following way:

> p <- ggplot(ssq, aes(x=year, y=-log(ssq)))
> p + geom_point() + facet_grid(me*gi~cs*rz)

and it works nicely, except that I would like to have, in naddition to the values of me, gi, cs and rz the name of the variable. I.e: if gi is 1, 2 and 3 I would like to have "gi = 1:", "gi = 2" and "gi = 3" as labels of the p[anels. I did it with ggplot, but I don't remember and I have lost the code ...

Just a small comment on the package: as I am using emacs with ess, I have to press "_" twice to get the underscore in the commands (as the first one is replaced with "->" and then reverted to "_") - would it be possible to change these in the next release with "." (but still provide an alias with "_")?

Thanks a lot
