Hi there If I create the array (matrix): A = fill(1, (2,3)) and then size(A), size(A,1), size(A,2) I get what I would expect. However, if I try size(A,3) I get 1 instead of what naively I would expect now to be an error. Why is it? In fact, for dataframes, asking for the size of a dimension …

Output of size(array, N) where N is greater than length(size(array))
