Hello

 

Because I want to use different true type fonts with latex, I'm using the
XeTeX typesetting engine for my sweave-documents. I'm using Lyx with Sweave
on a Windows 7 PC  and have set up LyX to work with XeTeX according to the
following instructions:

http://wiki.lyx.org/LyX/XeTeX

 

Because the input file for XeTeX is assumed to be in UTF-8 encoding, I set
the encoding under LyX - Tools - Language Settings - Language to "Unicode
(XeTeX) (utf8)". Accented letters that I write into the LyX-document are
correctly typeset in the final PDF-document. However, character strings with
accented letters that are read from Excel-files or other sources from within
R during the LyX-Sweave document compilation are not. For instance, the
German umlauts of the following example are not correctly typeset, when
"Unicode (XeTeX) (utf8)" is used as input encoding.

 

<<echo=F>>=

require(gdata)

x <- read.xls("http://www.schwerhoerigkeit.pop.ch/hoergeraete_test.xls",
stringsAsFactors = F)[2,2]

x

I do not have this problem with a Mac computer . I guess, this is because R
under Windows does not use UTF-8 encoding.   I tried to change the encoding
within R by doing the following

 

<<echo=F>>=

Encoding(x) <- 'UTF-8'

x

Unfortunately, this does not work. Does anybody have solution for this
problem?

 

Regards,

Erich
