Permutations (summary)
...and looking it up in z, the vector of all previously accepted ordered permutations. If its found then the while loop tries again and if it is NOT found then the permutation that samp just stored in z[i,] is accepted. The code is followed by a test generating 10,000 random permutations. ordered.perm2 <- function(N) { samp <- function() c(apply(matrix(z[i,] <<- sample(12,12),3),2,sort)) s <- vector(length = N, mode = "character") z <- matrix(nr = N, nc = 12) for(i in 1:N) while( (s[i]<-paste(samp(),collapse=" ")) %in% s[seq(len=i-1)] ) {...

Permutations
Dear R users, I?m a beginner user of R and I?ve a problem with permutations that I don?t know how to solve. I?ve 12 elements in blocks of 3 elements and I want only to make permutations inter-blocks (no intra-blocks) (sorry if the terminology is not accurate), something similar to: 1 2 3 | 4 5 6 | 7 8 9 | 10 11 12 ----------1st permutation 1 3 2 | 4 5 6 | 7 8 9 | 10 11 12 NO - - 3 2 1
