Hello, I create a certain number (n*m) matrices, that I would like to store. These matrices have different dimensions. As far as I know, for matrices of different dimensions, there's no alternative to a list.
Here's how I store them on the fly : my_list <- NULL for (i in 1:n) {for (j in (i+1):m) {my_list <- list(my_list,i_create_a_matrix(i,j))) } } But the indexation of the result is horrible ! (see below a simplified version, with no matrices created but i*10+j added to the list instead). Is there a cleaner way to get the same result ? Any help will be very welcomed.
