[R] Generate N random numbers with a given probability and condition

[Nelly Reduan]

Dear all,

I would like to generate N random numbers with a given probability and condition but I'm not sure how to do this.
For example, I have N = 20 and the vector from which to choose is seq(0, 10, 1). I have tested:

x <- sample(seq(0, 10, 1), 20, replace=TRUE, prob=rep(0.28, times=length(seq(0, 10, 1))))

But I don�t know how to put the condition sum(x) <= max(seq(0, 10, 1)).
Many thanks for your time
Nell
