If you also want 1,1,1 and so on, the number of these is n^n, (n choices for each of n slots.) In that case, you could use hcube from combinat.

Reiner Rho Trading Securities, LLC Chicago IL 60605 -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jesse Albert Canchola Sent: Friday, August 18, 2006 3:26 PM To: r-help Subject: [R] Permutations with replacement Is there a simple function or process that will create a matrix of permutations with replacement? I know that using the combinat package ###### begin R code ###### > library(combinat) > m <- t(array(unlist(permn(3)), dim = c(3, 6))) # we can get the permutations, for example 3!=6 # gives us > m [,1] [,2] [,3] [1,] 1 2 3 [2,] 1 3 2 [3,] 3 1 2 [4,] 3 2 1 [5,] 2 3 1 [6,] 2 1 3 ###### end R code ########## I'd like to include the "with replacement possibilities" such as 1,1,3 1,1,2 2,3,3 and so on. This will eventually be done on 8!=40,320 rather than the development version using 3! as above. If no function exists (I've Googled on CRAN with no palpable luck), then perhaps this is more of a bootstrap type problem.
