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.

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

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.)
