Hello.

Somebody knows how to write in R all the permutations of a given set?
For example, is the set is {a,b,c} I want the following:
a,b,c
a,c,b
b,c,a
b,a,c
c,a,b
c,b,a

library(gregmisc)
permutations(3, 3, letters[1:3])

gives

      [,1] [,2] [,3]
[1,] "a"  "b"  "c"
[2,] "a"  "c"  "b"
[3,] "b"  "a"  "c"
[4,] "b"  "c"  "a"
[5,] "c"  "a"  "b"
[6,] "c"  "b"  "a"

HTH,

Bernd
