[R] "Low Pain" Unicode Characters in pdf graph?

[Dennis Murphy]

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
