You need to provide a reproducible example, or as nearly reproducible as possible. You need to provide more information about your system (Windows?) -- the results of sessionInfo() would help. For example, I have no problem taking the standard deviation of a million-element vector: > set.seed(1001) > sd(runif(1e6)) [1] 0.2884210 > sessionInfo() R version 2.11.1 (2010-05-31) i486-pc-linux-gnu locale: [1] LC_CTYPE=en_US.UTF-8 LC_NUMERIC=C [3] LC_TIME=en_US.UTF-8 LC_COLLATE=en_US.UTF-8 [5] LC_MONETARY=C LC_MESSAGES=en_US.UTF-8 [7] LC_PAPER=en_US.UTF-8 LC_NAME=C [9] LC_ADDRESS=C LC_TELEPHONE=C [11] LC_MEASUREMENT=en_US.UTF-8 LC_IDENTIFICATION=C attached base packages: [1] stats graphics grDevices utils datasets methods base what happens on your system? sd( ______________________________________________ R-help@r-project.org 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.
