Hi, I thought that I had read somewhere that there was a really simple way to overlay the probability density function of a normal distribution over a histogram, after the histogram has already been plotted. Possibly a one word command.
I've found this email from the archives, but I don't think this is what I'm looking for. I thought there was something more simple than the curve function. http://tolstoy.newcastle.edu.au/R/help/05/04/3523.html R> x <- rnorm(100) R> hist(x, freq = FALSE) R> curve(dnorm, col = 2, add = TRUE) Is there a simple way to do this, or is my memory failing me? Thank you.
