Hi, Try this,
apply(expand.grid(letters[1:3], letters[24:26]), 1, paste,collapse="") [1] "ax" "bx" "cx" "ay" "by" "cy" "az" "bz" "cz" ?expand.grid HTH, baptiste 2009/12/14 Amelia Livington <amelia_living...@yahoo.com>: > > Dear R helpers, > > I am working on the scenario analysis pertaining to various interest rates. > In this connection I need to form the various combinations as under : > > Suppose I have two sets A = (a, b, c) and B = (x,y,z) > > Then I can easily form the cominations as > (ax, ay, az, bx, by, bz, cx, cy, cz) > > However, if I have 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.
