Dear R-experts---is there a relatively low-pain way to get unicode characters into a plot to a pdf device? pdf(file="cardsymbols.pdf") plot( 0, xlim=c(0,5), ylim=c(0,5), type="n") text(1,1, "♠") text(2,2, "♥") text(3,3, "♦") text(4,4, "♣") dev.off() (these are the characters that I need the most NOW, but this is a more generic question.) sincerely, /iaw ---- Ivo Welch (ivo.welch at gmail.com)

It is cited by the ?plotmath page as a way of getting at symbols. -- David Winsemius, MD Heritage Laboratories West Hartford, CT
Hi:
For your specific problem, one way is:
plot( 0, xlim=c(0,5), ylim=c(0,5), type="n", cex = 2)
text(1, 1, expression(symbol('\252')))
text(2, 2, expression(symbol('\251')))
text(3, 3, expression(symbol('\250')))
text(4, 4, expression(symbol('\247')))
More generally, David's advice is sound; see ?plotmath and focus on
the sections 'Other symbols' and 'References'; the last
reference
provides a summary table of standard symbols and their codes in
several formats.
HTH,
Dennis

Both are making use of Cairo, which uses UTF-8 and automatically embeds fonts. Regards Liviu
