Thank you. That's exactly what I was looking for.

If the ecdf is 'ecdf(x)', do just:
sample(x, size=whatever, replace=TRUE)

Hi All, Does anybody know if there is a simple way to draw numbers from an empirical distribution? I know that I can plot the empirical cumulative distribution function this easy: plot(ecdf(x)) Now I want to pick a number between 0 and 1 and go back to domain of x. Sounds simple to me. Any suggestion?
