[R] Get identical results for parallel and sequential?
Hi All, I have a question about R parallel computing by using snowfall. How can I set the seeds on parallel workers to get the same result as sequential mode? For example: > sfSapply(c(1,1),rnorm) [1] 1.823082 -2.222052 > rnorm(2) [1] -0.5179967 -1.0807196 How to get the identical result? Thanks.

Sorry. That was my first time to post, I was not sure if it worked or not.
