I think you need to escape the '\' character in your string by adding an extra
'\' in front of it. So try
pdf("junk.pdf")
par(family="mono")
plot(1,1)
text(1,1, "\\txx")
mtext("\\txx")
dev.off()

Onderwerp: [R] Tabs in PDF documents
Colleagues,
I am using R 2.5.1 on an Intel Mac (OS 10) to create PDF outputs
using pdf(); same problem exists in Linux (RedHat 9)
While adding text to the document with text() and mtext(), I
encounter the following problem:
In order to align the text, I have embedded tabs ("\t") in some of
the text. Each time I do so, I get the following error messages:
Warning: font metrics unknown for character 0x9
Warning: font width unknown for character 0x9
and the tabs are ignored. I have tied par() with and without
family="mono".
Is there a work-around available for this?
Dennis
COMMANDS:
pdf("junk.pdf")
par(family="mono")
plot(1,1)
text(1,1, "\txx")
mtext("\txx")
dev.off()
