Both of these work on my system:
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, "]"))) # FH
lines(ecdf(x), cex=.5)
plot(xs, cdf, type='l', ylim=c(0,1),
xlab=expression(x),
ylab=expression("Prob[X" <= "x]")) # PE
lines(ecdf(x), cex = 0.5)
