[R] Sweave and LaTeX beamer class

[Bernd Weiss]

Hi,

has anyonne experienced problems between the LaTeX beamer class and 
Sweave? The following code does not work properly:
#################################
\documentclass{beamer}

\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{ngerman}

\begin{document}
\frame{
  \frametitle{test}
test
<<>>=
 1+1
@ 
}
\end{document}
#################################

Below is the error code:
#################################
