Hi: One way to permute your sample 1000 times is to use the r*ply() function from the plyr package. Let s denote your original vector, randomly generated as follows: s - rbinom(800, 0.6) # simulates your Yes/No vector library(plyr) u - raply(1000, sample(s))# generates a 1000 x

Always fun to follow up your own posts The replicate() line should be v - replicate(1000, sample(s)) # generates an 800 x 1000 matrix Sorry for the bandwidth waste... Dennis On Mon, Oct 18, 2010 at 6:55 PM, Dennis Murphy djmu...@gmail.com wrote: Hi: One way to permute your sample
