See ?sample which has a default of replace = FALSE.
Usage:
sample(x, size, replace = FALSE, prob = NULL)
> N<-10
> sample(1:(2*N),N)
[1] 1 14 11 3 19 8 4 7 18 17

Subject: [R] repeat until function
Hi,
I'm in this situation:
I what to generate N random numbers(integer) that are different from each
other.
One suggestion:
tabel <- rep(NULL, N)
for (i in 1:N){
temp <- as.integer(runif(1,1,max))
if(temp in tabel) {
repeat (?) (temp <- as.integer(runif(i,i,max)))
until (?) ((temp in tabel) ==FALSE)
}
else{ tabel[i] <- temp}
I can't use repeat/until - don't exist....
Any suggestions?
Thanks
*Ragnhild*
