You were right, that I would run into trouble with all these "". However,
the second method doesn't work either. Somehow, the UTF8Sweave.sh file is
not found during the compilation of my document. It says "can't open perl
script .../bin/UTF8Sweave.sh: No such file or directory". I double checked
that a file with this name is present in the same folder as the original
Sweave.sh file and that the "Sweave" is changed to "UTF8Sweave" in the LyX
preference file. Any idea, what could be wrong?
Sorry, I forgot that if you make up your own command to be run by R CMD
then you need to give the full path to it, and you can't suppress the
.sh suffix. So your command should be
R CMD /path/to/UTF8Sweave.sh $$i
(where /path/to/ is the actual path to where you decide to keep this
file, which needn't be in rhome/bin).

Thanks again. Putting options(encoding="") into the R code chunk before
calling the read.xls function indeed did the trick. Now, I have one last
question: How can I edit the LyX preference file to call R with
options(encoding='UTF-8'). I prefer to edit the LyX preference file rather
than the Sweave.sh file, because I want to run R with UTF-8 only when I
use
XeTeX. By editing the LyX preference file, I assume it would be possible
to
define different R encoding setups for different converters.
One way would be to change
R CMD Sweave $$i
in
\converter "literate" "latex" "R CMD Sweave $$i" ""
to
echo "library(\"utils\"); options(encoding=\"UTF-8\"); Sweave(\"$$i\")" |
R --no-restore --slave
but you may run into trouble because there's an extra set of "" to go
around there, and I don't know how Lyx handles escaping all those quotes.
So probably an easier way to go would be to take the Sweave.sh file
that you've already edited, and copy it into UTF8Sweave.sh in the same
directory. Then you can change the Lyx preference line to
\converter "literate" "latex" "R CMD UTF8Sweave $$i" ""
and things should work. (Then you can restore the original Sweave.sh file
for cases where you don't
want UTF-8.)

Thank you! I edited the Sweave.sh file and it works now for reading
data
stored as R data files, but the read.xls function from the
gdata-package
does no longer work.
options('encoding'='UTF-8')
require(gdata)
read.xls("http://www.schwerhoerigkeit.pop.ch/hoergeraete_test.xls";,
stringsAsFactors = F)[2,2]
This gives NA as output and a warning that there was an invalid entry
for
the connection. Is there a way to use read.xls with UTF-8 encoding?
I don't know, you'd have to ask its authors. But you can probably set
options(encoding="") before calling it. (I'm assuming the read.xls() is
in
a code chunk in your Sweave file. I would guess that you don't need to
set
the encoding back to UTF-8 afterwards, but you might: it all depends on
when Sweave() opens its
output file.)

Putting \usepackage[cp1252]{inputenc} into my preamble is not an
option,
because XeTeX unlike LaTeX needs UTF-8 has input encoding. My goal
is
also
to have a LyX document that can be compiled both on Mac and Windows.
I usually compile my Lyx-Sweave documents by one click of a button
from
within Lyx. R code chunks are therefore executed by calling R from
the
command line. If anybody knows how to run R with
options(encoding="UTF-8")
from the command line under windows, that would be helpful.
The command that calls R during compilation is contained in this
file:
http://cran.r-project.org/contrib/extra/lyx/preferences
You can do it with a little work. If you look at the
rhome/bin/Sweave.sh
file, you'll see that
R CMD Sweave file.Rnw
just executes something like
echo "library(\"utils\"); Sweave(\"file.Rnw\")" | R --no-restore
--slave
What you want is to execute
echo "library(\"utils\"); options(encoding="UTF-8");
Sweave(\"file.Rnw\")"
| R --no-restore --slave
You could edit the rhome/bin/Sweave.sh file appropriately if you
always
want Sweave to use UTF-8, or you could edit your Lyx preference file
to
put
in a line like this instead of what it had.
