This is a problem because R makes frequent use of the "$" symbol, which toggles math-mode in LaTeX. As a result, where I have an odd number of "$"s in a chunk of R code, any LaTeX following that R code will appear highlighted green, as though it were in math mode.

I assume that you have the R bundle installed?  Are you sure that the
language is set to SWeave when you open .Rnw file?  Have you tried
putting empty lines before and after both "<<>>=" and "@" tags?  I
seem to remember a small issue with that in the SWeave bundle, if that
is the issue I might have a fix I can dig out.
