...ave say 5 variables, then total no of possible combinations will be 3^5 = 243. Thus, A = (a,b,c), B = (x, y, z), C = (l, m, n), D = (p,q,r), E = (s, t, u). Then may be my possble combination will start as (a, x, l, p, s), then next combination may be (a, x, l, p, u) and so on. The last combination (243rd in this case) may be (c, z, n, r, u) or something like this.   In R, is there any way to list all these 3^5 = 243 combinations?   Amelia [[alternative HTML version deleted]]
