I cannot reproduce the problem, the minimal Rnw file

**********************************************************

\documentclass[a4paper]{article}

\SweaveOpts{keep.source=FALSE, echo=TRUE, eval=FALSE, height=4}

\begin{document}

<<>>=
print(1:10)
@ 

\end{document}

**********************************************************

produces as expected

**********************************************************

\documentclass[a4paper]{article}

\usepackage{Sweave}
\begin{document}

\begin{Schunk}
\begin{Sinput}
> print(1:10)
\end{Sinput}
\end{Schunk}

\end{document}

**********************************************************

for me, no evaluation happening. If I change to eval=TRUE then I get
printed output.

Best,
Fritz
