Hi Andrew,
Do you want to put the symbols you described as a legend in a plot? If so,
here is one way:
x <- rnorm(3)
plot(x, pch = 16, cex = 1.1, col = 1:3)
legend('topleft', ncol = 3,
c(expression(alpha), expression(beta), expression(gamma)), pch = 16,
cex = 1.1, col = 1:3)
Is you do not want to use legend, but place the symbols in each plot, then:
plot(x, pch = 16, cex = 1.1, col = 1:3)
text(1.05,1.01*x[1], expression(alpha) )
text(2.05,1.01*x[2], expression(beta) )
text(2.95,1.01*x[3], expression(gamma) )
should get you close.
See ?text, ?expression and ?legend for more information.
HTH,
Jorge
