This could well be a package-specific issue, and so perhaps not for R-devel.
The author of the relevant package is CC'd in any event.
I'm seeing some odd behavior from Sweave with keep.source=TRUE when using
driver=cacheSweaveDriver from the cacheSweave package.
It would seem that code chunks with keep.source=TRUE aren't being parsed
correctly; the corresponding Schunk starts at the *very top* of the Rnw file,
snippet shown below.
The error seems specific to R 2.12.0; cacheSweave + keep.source=TRUE seems to
work ok in R 2.11.
Many thanks
Simon
Version details:
R version 2.12.0 Under development (unstable) (2010-09-10 r52888)
cacheSweave package 0.4-4
Sweave invocation and output:
> Sweave("test.Rnw",driver="cacheSweaveDriver")
Writing to file test.tex
Processing code chunks ...
1 : term hide (label=setCache)
2 : echo term verbatim (label=rnorm)
3 : echo keep.source term verbatim (label=runif)
4 : echo term verbatim (label=summary)
You can now run LaTeX on 'test.tex'
Bad Schunk:

\end{Sinput}
\end{Schunk}
