R help - Sep 2009 - generate random number without repetition

Hi all,

I would like to generate ~18K random number from range 1 to ~33K.

I was thinking to use round(runif(18000,1,33000)), however the some random
numbers generated are repeated.

Do you know a better way?

thanks,
phoebe

if you want to sample integers in [1, 33K] without replacement:

theSample = sample(33000, 18000)
