Hello, I'm trying to permutate the data in the columns of a matrix. I don't want any replacement but I would like each unique combination/ matrix saved as a variable. 1A 1B 1C 2A 2B 2C 1 0.42 0.14 0.84 0.78 0.08 0.44 2 0.28 0.34 0.02 0.85 0.23 0.19 3 0.56 0.43 0.68 0.29 0.34 0.29 4 0.54 0.33 0.65 0.45 0.96 0.63 5 0.44 0.58 0.84 0.34 0.17 0.53 Any suggestions would be greatly appreciated! Thanks [[alternative HTML version deleted]]

Depending on what you are doing, you may think you want permutations when in fact you want combinations. Anyway, see ?permutations in the gtools package.
