Sweave uses the fancyvrb package, which allows quite a lot of customization. I don't think it would be easy to use Sweave to apply different highlighting to different parts of R code, but you could use fancyvrb directly.

When combining Sweave and beamer, you need to remember the opening

\begin{frame}[containsverbatim]

but that's probably true for \begin{verbatim} too.

I've also used the listings package (not with beamer), but didn't stick with it, I think because I didn't like the default style and was too lazy to customize it.
