The two documents were actually different, which I didn't notice
yesterday. One had different encoding. Thanks for your help Duncan.
Unfortunetly the other problem still exists. My R or Sweave seems not to
be able to work with utf-8 encoding. Everything works fine with
latin-1, though. I could check my assumption if there was a possibility
to switch R from latin-1 to utf-8. Does anybody have an idea how that
might work?

Hi Roland,
thanks for your answere. I actually tried out a different, smaller
Latex-header and the sweave-process suddenly worked. So I copied
parts of the old header into the new one, to check what part is
causing the trouble. In the end I had two documents with identical
content. The new document worked fine with Sweave the other still
gave out the error-message. If anybody has experienced that problem
before, and knows an answere, please let me know.
This sounds like you have discovered homeopathic properties in
Sweave! It will be serious if input files remember errors even after
they have been removed.
But I think it's more likely that the files just look the same in your
editor, but are actually different in some way you don't see.
Candidates:
- the encoding: maybe your editor is recognizing the encoding, and
automatically displaying similar content from different input.
- non-printing characters: maybe your editor is skipping some.
I'd suggest doing a binary compare on the two files to see what the
differences are. I think you are on Windows (but I may be misreading
the quotes below); I recommend Beyond Compare (a shareware compare
utility). It has a hex viewer plug-in that could show you a detailed
comparison. I imagine diff on Unix has something similar.

Unfortunaetly I also still have an encoding problem with the new
documt, that ran through Sweave. If I use "ISO-8859-15" fontencoding
in my editor and "latin1" for input encoding in my Latex-document
everything works fine. If I keep both in "utf8", as I would like it,
german mutated vowels (Umlaute) aren't displayed correctly.

Subject: [R] Sweave encoding problem
Hello,
Sweave seems to have trouble processing german letters in R.
For example, my noweb R-input looks like this.
<<>>=
Oberflächenfehler = c(4, 11, 6, 2, 7, 9)
@
If I send it through Sweave, I get the following error message.
error: chunk 1
Error in parse(text = chunk) : unexpected input in "Oberflä"
extra: Warning message:
In readLines(f[1]) :
underfull last line in "C:\...."
(my R is in german, so I needed to translate the error message
myself.)
I got the impression, that this is an encoding issue of Sweave,
since the input typed into R directly works just fine. The
encoding I use in my noweb document is utf8.
I don't think it has something to do with German letters.
I saved the following text in a file 'sweavy.Snw':
\documentclass{article}
\begin{document}
Hello World!
<<>>=
1+1
@
<<>>=
Oberflächenfehler = c(4, 11, 6, 2, 7, 9)
@
\end{document}
This is what happened in R:
library(utils)
Sweave("sweavy.Snw")
Writing to file sweavy.tex
Processing code chunks ...
1 : echo term verbatim
2 : echo term verbatim
You can now run LaTeX on 'sweavy.tex'
sessionInfo()
R version 2.7.0 (2008-04-22) i386-pc-mingw32
locale:
LC_COLLATE=English_United States.1252;LC_CTYPE=English_United
States.1252;LC_MONETARY=English_United
States.1252;LC_NUMERIC=C;LC_TIME=English_United States.1252
attached base packages:
[1] stats graphics grDevices utils datasets methods
base
And also the dvi looked fine after processing "latex sweavy.tex"
To make things sure, I did in my editor (GNU Emacs 22.1.50.1)
C-x RET f utf-8
to change set-buffer-file-coding-system to utf-8.
Still works fine.
Maybe this helps you further to track down the reason for the
problem?!?
Best,
Roland
