I think this may have been fixed in the patched version. Could you give it a try to confirm? If not, please send me a simplified version of the file, and I'll see what's going wrong.

\SweaveOpts{engine=R, keep.source=TRUE}
\SweaveOpts{eps=FALSE, prefix.string=snArt/4lmetc}

The attempt to process the file through Sweave generates the error:

Sweave("4lmetc")
Writing to file 4lmetc.tex
Processing code chunks ...
  1 : keep.source term verbatim
Error in file(srcfile$filename, open = "rt", encoding = encoding) :
   cannot open the connection
In addition: Warning message:
In file(srcfile$filename, open = "rt", encoding = encoding) :
   cannot open file '4lmetc': No such file or directory

The same file processes through Stangle() without problems.
If I comment out the \Sweaveopts lines, there is no problem,
except that I do not get the options that I want.

This processed fine in R-2.11.1
