[R] Spellchecking Sweave documents

[Michael Hoffman]

I have been using Aspell on a Linux system, but it doesn't
understand the noweb chunks, which I'd rather it not spellcheck. I
can run it on the generated .tex files, but then changes I make
during the spellcheck will not be propagated back to the original
source. Any suggestions on how to spellcheck Sweave documents?

I see from a search that some people seem to be trying Flyspell on 
Emacs. I'd rather have a solution that runs outside of Emacs, but if 
anyone is using Flyspell successfully, I'd love to know of their 
experiences.
