Yes, that's right. > > .Random.seed is a vector with 626 numbers, but set.seed() only accepts a > integer number. > What do I need to do for saving .Random.seed and using the saved > .Random.seed for setting set.seed() ? As Prof Ripley pointed to me in a post a while ago out, the help ?.Random.seed specifies that .Random.seed is the PRNG state, not the seed itself. So assign .Random.seed to a variable, and then assign the variable to it later: > runif(3) [1] 0.919502 0.361622 0.847657 > r <- .Random.seed > runif(3) [1] 0.3898361 0.4727398 0.5698874 > .Random.seed <- r > runif(3) [1] 0.3898361 0.4727398 0.5698874 Cheers, Gad -- Gad Abraham Department of Mathematics and Statistics The University of Melbourne Parkville 3010, Victoria, Australia email: [EMAIL PROTECTED] web: http://www.ms.unimelb.edu.au/~gabraham ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
