This is just a quick hack, it doesn't yet work as well as I would like but it is better than nothing.

Must have the R bundle installed. Easiest way to install is to open the bundle editor ("Bundles" > "Bundle Editor" > "Show Bundle Editor") and copy this file over the R syntax file from the R bundle. Then "Reload Bundles" or restart TextMate.
