[ESS] Preview-latex for noweb (.Rnw) files

[Ista Zahn]

Hi,
I'm not sure if this is more appropriate here or on the auctex list...

Preview-latex works great in my .tex files, but not in my .Rnw files.
Basically I think it tries to run latex on the .Rnw file, which of
course does not work. Is it possible to get Preview-latex working with
Sweave documents? Any hints?

Thanks,
