[R] Evaluate output after each rep()

Hi R-Help,

I'm trying a develop a test simulation where i evaluate the probability of not getting a value of 100 from the function rbinom(6000, 200, .5) [indeed, a very small probability]. At the end of each rep, I would like to evaluate the output, continue with the loop if the output contains the value 100, stop if the output lacks a 100.

How do I get R to evaluate the output after each rep?

>sim <- function(nn){
> for (ii in 1:nn){
> ee=rep(rbinom(6000, 200, .5), ii)
> if (any(ee==100))
> }

Thanks,
Matt MacManes
