Dear R-help, Suppose I write a script that looks something like this:
#### script.R set.seed(something) x <- rnorm(100) y <- runif(500) # bunch of other stuff save.image() ### end of script.R Now, I give you a copy of my script.R (with the set.seed statement removed, of course) together with the .RData file that was generated by the save.image() command. Question: 1) can you tell me what my original set.seed() value was? (I wouldn't be able to figure it out, but maybe someone can) 2) is it possible *in principle* to figure out what set.seed was, given the above? (OK, being able to figure it out in 2*10^68 years doesn't count, but within a couple months is acceptable.) 3) does the answer change if there is a remove(.Random.seed) command right before the save.image() command? Any thoughts would be appreciated. Cheers, Jay *************************************************** G.
