Hi all.
I am using R 1.8.1 on MacOS X (RAqua) to plot some graphs for my
diploma thesis. I had some problems getting the german umlauts
(a-dieresis, for example) into the output file using the pdf device
driver. The umlauts appeared as 'white holes' in the final pdf.
After hours of twiddling I found out that by changing the encoding
to WinAnsi, everything worked like a charm.
Just have a look at this:
pdf("winansi.pdf",encoding="WinAnsi")
plotSymbols()
dev.off()
pdf("isolatin1.pdf",encoding="ISOLatin1")
plotSymbols()
dev.off()
and the generated output in
http://www.shredda.de/winansi.pdf
and
http://www.shredda.de/isolatin1.pdf
respectively.
The former shows the character a-dieresis on position 228.
The latter shows just -ahem- nothing. Since iso8859-1 aka
latin 1 ist supposed to have a-dieresis on position 228 (dec),
I don't get the point.
If this is the preferred way to get umlauts into a pdf, it should
be noted somewhere. Otherwise, what did I miss?
Thanks in advance.
Regards,
Christian
