[R] How does Sweave write to a file?

[Arnau Mir Torres]

Hello.

I need that Sweave writes R output to a file. To do it, I put the following into the foo.Rnw file:


\documentclass{article}
\usepackage{Sweave}
\begin{document}

...

<<echo=F>>=
x <- rnorm(100)
y <- rnorm(100)
sink("foo.txt")
summary(lm(y~x))
sink()
@

...

\end{document}


When I run:

R CMD Sweave foo.Rnw

R responses:

Warning message:
In sink() : no sink to remove, 

and It doesn't work. Somebody knows how I can fix it?

Thanks,

Arnau.
