[R] Trouble with Sweave and Beamer

[Lorenzo Isella]

Hello,
And thanks for the prompt reply.
I also bumped into this thread shortly after posting

where it looks like that the "fragile" option gets the job done (at 
least on my machine for my example), though I do not know (yet) what it 
stands for.
I will post again if I have further problems
Cheers

Lorenzo
