set.seed() sounds fine. On reading this, it occurs to me that I could
probably do something like this that just set the value of .Random.seed in
R code (just copying what RNG_Init() does to set .Random.seed from
time()), without mucking with the C code (although a lot of the details of
RNG settings etc. seem to be in C rather than R code at the moment).
thanks,
Ben
