I have a list that gives me the number of occurrences of numbers 1, 2, 3 and 4.
Sometimes a single in a casa just appears 0 and 1, in others only 2, and every combination you can think of. Eg > Caso [1:2] $ `9` 0 1 2 10 $ `13` 0 2 2 4 Can I turn it into a matrix consisting of 4 columns in which I put the number of occurrences of the previous numbers, and for cases where it does not appear any of those values put 0?
