Hi: Your R terminology needs a little work, but I think this is what you're after: # read your example data from e-mail into an R session dd <- read.table(textConnection(" Ind1 11 00 12 15 28 Ind2 21 33 22 67 52 Ind3 22 45 21 22 56 Ind4 11 25 74 77 42 Ind5 41 32 67 45 22"), header

To pick random elements to sample, you can just use the sample function sample(1:5,3,replace=T/F) # pick true or false as needed for your data. If you replicate this, you should have no problem. replicate(100,function() return(sample(1:5,3,replace=T/F))) This will be plenty fast, but if you get

Hello, I am a R beginner and hoping to obtain some hints or suggestions about using permutations to sort a data set I have. Here is an example dataset: Ind1 11 00 12 15 28 Ind2 21 33 22 67 52 Ind3 22 45 21 22 56 Ind4 11 25 74 77 42 Ind5 41 32 67 45 22 This will
