I have a function called nnmf which takes in one matrix and returns two matrices. for example,
> X [,1] [,2] [,3] [,4] [1,] 1 4 7 10 [2,] 2 5 8 11 [3,] 3 6 9 12 > z=nnmf(X,2) > z$W [,1] [,2] [1,] 0.8645422 0.6643681 [2,] 1.7411863 0.5377504 [3,] 2.6179287 0.4111063 > z$H [,1] [,2] [,3] [,4] [1,] 1.14299486 1.692260 2.241279 2.79030 [2,] 0.01838514 3.818559 7.619719 11.42087 ---------------------------------------- Now I would like to run it many times -- z2 = nnmf(X,2) z3 = nnmf(X,3) z4 = nnmf(X,4) z5 = nnmf(X,5) ... But I would like to do it automatically , something like - xprocess<-function(max_val) { for (iter in 2: max_val) { zz = sprintf( "z%s", iter ) zz <-nnmf(X,iter) } } xprocess(10) ---- But how could I keep collection of my results each run? Shall I have a data structure to keep appending results? something like theta = {} ? which data structure to choose to keep multile objects? Thanks!
