Sweave - if \Sexpr{} than \SweaveInput{"my.Rnw"}

If you want to program Sweave documents, you can try the knitr
package. This case will be something like:

<<>>=
paper <- TRUE # or change it to FALSE
@

<<child=if (paper) 'my1.Rnw' else 'my2.Rnw'>>=
@

i.e. you use the logical variable 'paper' to control which child
document to include in the parent document. See

Depending on an R computation I would like to include an Sweave documents
in the main Sweave document.
How can I do it?

So I was thinking .... to use Latex features :

\newif\ifpaper

\ifpaper

\SweaveInput{"my1.Rnw"}
\else
 \SweaveInput{"my2.Rnw"}
\fi

But how do I set paper to true or false given an \Sexpr ??

\papertrue % or

\paperfalse


Any ideas?


cheers
