For a given numeric vector v of length n and sum s, is there a ready- to-run code that returns every combination of v in n summing up to s? Example for n=3 and s=2: v <- c(2, 0, 0) # find some coding here that returns [1] 2 0 0 [2] 1 1 0 [3] 1 0 1 [4] 0 2 0 [5] 0 1 1 [6] 0 0 2 Thanks S?ren

Function comb() in pkg:forensim does just that. -Peter Ehlers
