R help - Dec 2008 - Re sampling from an ECDF

Good day everyone,

I have about 500 values to generate my ecdf.
Now I want to sample 2000 values i.i.d. distributed according to my ecdf.

Is it possible to sample from an ecdf? 
If yes, I would appreciate your help.

Martin

say 'x' is your sample, then try

sample(x, 2000, replace = TRUE)


I hope it helps.

Best,
Dimitris
