I can confirm the " instead of ≤, using the default X11 device.
I use a Gentoo amd64 box, R-2.13.0.
Using ylab=expression("Prob[X" <= "x]") didn’t change things.
(The " might actually be a ″ (DOUBLE PRIME); it is hard to tell.)
OTOH, using a utf8-encoded ≤ works:
set.seed(6)
x<- rnorm(30, 100, 20)
xs<- seq(50, 150, length=150)
cdf<- pnorm(xs, 100, 20)
plot(xs, cdf, type='l', ylim=c(0,1),
xlab=expression(x),
ylab=expression(paste("Prob[X ≤ x]")))
lines(ecdf(x), cex=.5)
I ran the scripts in ESS, but that shouldn't affect the plots.
