[R] Sweave: option keep.source=TRUE and package cacheSweave

[Renaud Lancelot]

Dear all,

When I use the cacheSweave package together with the Sweave option
keep.source = TRUE, all the LaTeX code before the Sweave code chunk is
included in the TeX file to be compiled. For example, with the
following Sweave file

\documentclass[12pt]{article}
\usepackage[nogin]{Sweave}

% Sweave options
\SweaveOpts{keep.source=TRUE, strip.white=TRUE, eps=FALSE, pdf=TRUE}

\begin{document}

Blabla.

<<optionsR, results=hide>>=
setCacheDir("./cache")
library(MASS)          ## just an example
@

\end{document}

I get the following TeX file:

\documentclass[12pt]{article}
\usepackage[nogin]{Sweave}

% Sweave options


\begin{document}

Blabla.

\begin{Schunk}
\begin{Sinput}
> \documentclass[12pt]{article}
> \usepackage[nogin]{Sweave}
>
> % Sweave options
> \SweaveOpts{keep.source=TRUE, strip.white=TRUE, eps=FALSE, pdf=TRUE}
>
> \begin{document}
>
> Blabla.
>
> <<optionsR, results=hide>>=
> setCacheDir("./cache")
> library(MASS)          ## just an example
\end{Sinput}
\end{Schunk}

\end{document}

When I set option keep.source = FALSE, the result is as expected. Is
there any possibility to use keep.source = TRUE with cacheSweave?
