Hi Marc,
the R2HTML package was actually the problem. It is embarrassing since now I remember that I have read about it a long time ago and I think even used the option to solve it. I am also using Tinn-R which loads R2HTML by default.
And you were also right that the solution is in the Sweave FAQ: after adding "options(SweaveSyntax="SweaveSyntaxNoweb")" into a chunk of my .Rnw file, it works!
Thanks again for your help.
Best,
Wern

Chuck,
I may very well be wrong and I was going from

That being said, I cannot now (on OSX) replicate the problem, so unless

The only other conflict that I know of is if the R2HTML package
