Dear all, I have the following list, "aa", composed of two 3*3 tables. I would like to use "apply" function to summarize it, but "apply" cannot handle "list". I want to do it without using any interation.
1. Is there any function like "apply" for list? 2. Is there any way to transform that "list" to a 2*3*3 "array"? thanks cahn ----------------------------------------- >aa [[1]] [,1] [,2] [,3] [1,] 1 3 1 [2,] 2 0 1 [3,] 1 1 0 [[2]] [,1] [,2] [,3] [1,] 1 3 1 [2,] 2 0 1 [3,] 1 1 0 I would like to avoid any iteration ------------------------------------------------- Ahn, Chaehyung (cahn) Ph.D. Alpha-Gamma Technologies Inc.
