R help - Oct 2007 - Sweave and LaTeX

Hi
I started using Sweave and LaTeX but have a (smaller) problem. 
As I am not yet very fluent in LaTeX I do the following: I texify my snw-file to
look for errors in my LaTeX and correct them.
However, if I have the following chunk, I get an error when texifying:

...
\usepackage{Sweave}
...


<<echo=F,
results=tex>>workdr<-('c:/aaa/Projekte/IOT2005/Bericht/Workingpapers')
setwd(workdr)
xtable(table_nzo,caption="Importg?ter, die nicht einem NOGA-Sektor
zugeordnet werden k?nnen")
@

The problematic line is the last one before @. If I comment it out, I get no
error.

The error in the LaTeX log is 

! Missing $ inserted.
<inserted text> 
                $
l.26 xtable(table_
                  nzo,caption="Importg?ter, die nicht einem NOGA-Sektor
zuge...

? 
! Emergency stop.
<inserted text> 
                $
l.26 xtable(table_
                  nzo,caption="Importg?ter, die nicht einem NOGA-Sektor
zuge...
End of file on the terminal!


Any idea what I am doing wrong?

Maybe a dumb question, and sorry if this is the case, but do you run
Sweave on your Snw file ? Because you must do it first to get a .tex
file which will be passed to latex. If you directly run TeX on your
Snw file, it can't work.

HTH,
