sum.x=sum(x) while(sum.x!=100) x=rpois(50,2) I have tried this, but this can really take some time. In fact, I would suggest an similarly "fraudulent" activity, draw 49 values, and set the last nonrandomly to the difference between 100 and the sum of the 49 values if this difference is a.) nonnegative and b.) not too extreme (say more than three lambdas out). This is "as random" as the previous approach, maybe even more.
