I have taken the liberty of scaling the problem down to something more digestible and have changed lines 5 and 7 in your code nsamples=10 sampsize=5 i=0 y=matrix(rnorm(nsamples*sampsize,50,3),nrow=nsamples) s=matrix(NA,10,5) for(i in 1:10){ s[i,]=sample(y,5,replace=T) } HTH Pete -- View this message in context: http://r.789695.n4.nabble.com/IMPORTANT-PLEASE-HELP-ME-tp4650676p4650692.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
