As a principle, you want list_of_vecs <- vector("list", 10) to avoid extending the list on each iteration. However, a simpler way is replicate(10, rnorm(10), simplify=FALSE) (where the simplify bit prevents conversion to 10x10 matrix) or lapply(1:10, function(i) rnorm(10)) -- Peter Dalgaard, Professor, Center for Statistics, Copenhagen Business School Solbjerg Plads 3, 2000 Frederiksberg, Denmark Phone: (+45)38153501 Office: A 4.23 Email: pd....@cbs.dk Priv: pda...@gmail.com ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
