[Rd] An idea: Extend mclapply's mc.set.seed with an initial seed value?

2012-11-02 Thread Ivan Popivanov
Hello, Have been thinking that sometimes users may want each process to initialize its random seed with a specific value rather then the current seed. This could be keyed off depending whether mc.set.seed is logical, preserving the current behaviour, or numerical, using the value in a call to set.

If CRAN were a passive repository, the discussion about its policies would not be relevant to this list e.g., SourceForge. However, the development of R and its packages are very intimately connected to the CRAN repository policy. I doubt any of the players in building our current R ecosystem

I appreciate your problem, and getting reproducible random generator results on a parallel system is something to be careful about. However, I would avoid making it too easy to have a fixed seed. In earlier days there were mistakes too often made by users inadvertently using the same seed over
