Is this what you want: > random <- expand.grid(R1 = 1:5, R2 = -(1:5)) > result <- cbind(F1 = 10, F2 = 100, random) > > result F1 F2 R1 R2 1 10 100 1 -1 2 10 100 2 -1 3 10 100 3 -1 4 10 100 4 -1 5 10 100 5 -1 6 10 100 1 -2 7 10 100 2 -2 8 10 100 3 -2 9 10 100 4 -2 10 10 100 5 -2 11 10 100 1 -3 12 10 100 2 -3 13 10 100 3 -3 14 10 100 4 -3 15 10 100 5 -3 16 10 100 1 -4 17 10 100 2 -4 18 10 100 3 -4 19 10 100 4 -4 20 10 100 5 -4 21 10 100 1 -5 22 10 100 2 -5 23 10 100 3 -5 24 10 100 4 -5 25 10 100 5 -5
