Dear MacRs;
I have been having this problem for a while, but thought that when I
updated to 2.11.1 that it might get fixed, but just did that and it
persists. When I use plotmath functions, I see little empty boxes
where I should be seeing theta's and phi's:
require(graphics) # the first plotmath example
x <- seq(-4, 4, len = 101)
y <- cbind(sin(x), cos(x))
matplot(x, y, type = "l", xaxt = "n",
main = expression(paste(plain(sin) * phi, " and ",
plain(cos) * phi)),
ylab = expression("sin" * phi, "cos" * phi), # only 1st is
taken
xlab = expression(paste("Phase Angle ", phi)),
col.main = "blue")
axis(1, at = c(-pi, -pi/2, 0, pi/2, pi),
labels = expression(-pi, -pi/2, 0, pi/2, pi))
# -- no phi's or pi's or warnings ---
How do I identify which library should be replaced or repaired or
added to my PATH or which option set?
Have searched archives and FAQs, but maybe I'm not using same terms or
understanding what I am being told.
