How can I get the same stream of random numbers in R and S? I know one of the generators in R is Super-Duper also used in S-plus,
Sorry, but no, it isn't quite the same as I understand them. S-PLUS skips members of the sequence occasionally. But it depends what you mean here: S-PLUS != S and I very much doubt you have S. I don't know why you want to do this: if you use any of the built-in operations (such as rnorm) you will get different answers as different algorithms are used. If all you want is a stream of runif() type, implement your version on both systems to be sure.
