Dear list, I have this problem, please your advice. I have list A that contains two matrix elements: [[1]] a b [1,] 2 1 [2,] 3 2 [3,] 3 2 [[2]] c d [1,] 3 5 [2,] 3 1 [3,] 2 3 and list B, that also contains 2 matrices: [[1]] e f g [1,] 1 20 30 [2,] 2 40 50 [3,] 3 60 70 [4,] 4 80 90 [5,] 5 100 110 [[2]] h i j [1,] 1 10 20 [2,] 2 20 30 [3,] 3 30 40 [4,] 4 40 50 [5,] 5 50 60 Now I want to match each column of list A with each row of list B in such a way that element 1 of list A corresponds to element 1 of list B (and element 2 of A with 2 of B). So, in total there will be 4 new matrices, 1 for each column of list A. For example, for column a of list A the new matrix will be: 2 40 50 3 60 70 3 60 70
