[R] Sweave and LaTeX beamer class

[David Whiting]

Hi Bernd,

I think it is because you are trying to place a chunk of R code within
a LaTeX command. I'm not sure that Sweave will be able to handle
that. In situations analogous to this I process the R chunk earlier in
my document and create an object that I then access in the LaTeX chunk
using \Sexpr{}.  Re-working your example might be something like this
(untested):

#################################
\documentclass{beamer}

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

\begin{document}

<<>>=
x <- 1+1
@ 

\frame{
  \frametitle{test}
test \Sexpr{x}}
\end{document}
#################################
