Hi Daniel, Turns out, your code, however simple, is quite elegant for my needs (sometimes I overanalyze :O). Here is my last code to do what I need to do:
####### begin R code ######## # generate a matrix of ten thousand rows of 1-8 z <- t(matrix(rep(1:8,10000),8,10000)) library(Matrix) # use the R sample function in a loop to sample each line with replacement zcomb=Matrix() for (i in 1:dim(z)[1]) { z1 <- t(matrix(sample(z,8,replace=TRUE))) zcomb = rbind(zcomb,z1) } zcomb ####### end R code ######### Regards, Jesse A.
