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.
