Dear All I would like to draw a picture with the density curve of a normal distribution over a histogram of a set of random numbers extracted from the same normal distribution. Is that possible?
To quote Simon `Yoda' Blomberg: "This is R. There is no if. Only how."
(see fortune("Yoda"))
Try:
R> x <- rnorm(100)
R> hist(x, freq = FALSE)
R> curve(dnorm, col = 2, add = TRUE)
Z
Thanks in advance, Paul
