in /usr/lib/R/etc/Rprofile.site but I get the following error Error in rm(.Random.seed) : cannot remove variables from base namespace [Previously saved workspace restored] and it is as if the set.seed() call didn't work, since I get the same random values. > rnorm(1:10) [1] -1.3618103 0.4241701 1.0720076 0.2208145 -0.5375314 -0.4846588 [7] 0.7576768 0.6527407 -0.6868786 0.8718527 If I do > set.seed(Sys.time()) > rnorm(1:10) [1] -0.6165650 0.6305187 -0.9316815 0.6034638 -0.8593514 -1.0243644 [7] -0.1050344 0.4408562 -0.3466161 0.4058430 manually, within the session, the seed seems to be changed as requested. Am I doing something wrong?
