Yes, that's what set.seed is intended to do... otherwise don't use set.seed (and make your work unreproducible). > My question is in order to run a true random sample, We have to disappoint you: Your computer cannot generate "true random samples". > wouldn't I have > to use the runif function? And then deliminate the sample to show the No, if you want integers, the sample above fits perfectly well. > numbers that lie between 4 and 6? If that's the case, how do I do that?
