R help - Sep 2004 - Sweave echoing comments (again)

Hello,

I try to document some R scripts for my collegues and observed the 
problem, that Sweave strips comment lines away.

As a small example I write in an Rtex file:

\begin{Scode}
## a small example
test() # line comment
\end{Scode}

... the .tex file generated by Sweave only contains:

\begin{Schunk}
\begin{Sinput}
  test()
\end{Sinput}
\end{Schunk}


... and all the comments are lost. Looking into the archives, I found, 
that such a question appeared already some months ago. Are there any 
advances or workarounds doing such things today?

Thank you in advance!

Thomas P.

Hi!

I observed it also. There are cases where it is not desirable. It will be quite
helpfull, if possible, to have a parameter that allows one to switch of removing
the #comments.

The problem is that the parser does not keep the comments, and I need
to parse & deparse the source in order to know when expressions are
complete, such that I can insert the ourtput in the right places.

Currently there is no way of keepng the comments in Sweave code
chunks.

Best,
Fritz

PS: I am promising a workaround for quite some time now, but haven't
had the time to code that yet, so don't hold your breath.
