[R] arrays of lists in R ("cell arrays" in Matlab)

Dear all

I would like to have some data in the form of a 2-dimensional array (matrix) of lists, so that I can easily find the desired list object by indexing the structure by rows and columns. In matlab there exists a data type called "cell array": a matrix of "cells", which are composite objects very similar to R lists.

I know that in R you can create 1-dimensional arrays of lists, either with the vector() function or by making a list of lists, but it is not clear to me whether it is actually possible to have 2-dimensional arrays of lists.

thank you very much for any suggestion
