R help - Sep 2010 - How to comment out entire code parts in Sweave files

Hi,

I am wondering if there is any convenient way to comment out an entire region of
a Sweave file which comprises R and Latex code. Currently I'm doing it for
the R
and Latex parts separately or transfer the unwanted part into a different file. 
But both are not great solutions. (I am doing this when updating old files and 
debugging)

Is there a way to do this with an equivalent of \iffalse \fi or is there some 
"stop" command after which Sweave just stops processing?

Thanks a lot for any suggestions.

Prefixing each line with % should work, if you're starting in LateX mode.

Hello Werner, 

good question. 

According to this source:
http://devdaily.com/blog/post/latex/multi-line-comments-in-latex-begin-123-
comment-125-verbatim
this can be done with
\usepackage{verbatim} 
and 
\begin{comment}
This is my comment.
Note that it can span multiple lines.
This is very useful.
\end{comment}\begin{comment}
