I get a double quote mark in place of <= in the y-axis label when I run the following. 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) The problem also occurs if I use instead ylab=expression(prob(X <= x))) All is well if I remove "=" but I need <=.
