Hi,

Sweave for some reason does not respect encoding setting in pdf.options. Everything is OK with ps.options. Thus when using non-default encoding for graphs, resulting graphics eps file is correct, but pdf file is not. Workaround is very simple, just use latex->dvips->ps2pdf chain to get the intended pdf document. I tried to find the explanation for this, but I did not find anything. If this is documented behaviour, I am sorry for the disturbance.

After Sweaving the file below, pdflatex and latex->dvips->ps2pdf will produce different pdfs. The tex file compiled succesfully in Ubuntu 8.04, and TeXLive 2007.

Sincerely yours,

Vaidotas Zemlys

Note the Lithuanian letters in latex will not display correctly, you need
additional package. This does not matter to R, since we use Unicode and pass the
correct encoding.
