R documentation with Roxygen? [closed]

Answer 1

I'd like to start using it, but as far as I know it doesn't yet support S4 classes, which I use extensively.

Answer 2

Yes, I use it all the time (in five packages and counting). It's fantastic! With it I managed to create a complete R package (stringr) in about five hours.

I recently submitted a patch to get a 10-fold speed up, which makes it even nicer to use.
