[R] which data structure to choose to keep multile objects?

I have a function called nnmf which takes in one matrix and returns two matrices. for example, X [,1] [,2] [,3] [,4] [1,]147 10 [2,]258 11 [3,]369 12 z=nnmf(X,2) z$W [,1] [,2] [1,] 0.8645422 0.6643681 [2,] 1.7411863 0.5377504

Re: [R] which data structure to choose to keep multile objects?

your could try something like this: xprocess-function(max_val) { result - list() for (iter in 2: max_val) { zz = sprintf( z%s, iter ) # use 'character' for indexing the list result[[as.character(iter)]] -nnmf(X,iter) } result } xprocess(10) On Fri, Nov 6, 2009 at 6:58
