If you have R 1.0.0 (or 0.99.0) use the function set.seed, as in
set.seed(54321). If not, we suggest you upgrade (although it can be done by
setting .Random.seed: see ?Random).
I am not sure what you are doing, but as it is often helpful not to
re-invent the wheel you might like to look at package boot.
