Answer 1

I think the reason for that is because you're trying to call an index number that doesn't exist for r. From what I can see, all r equals is [[x,y]] meaning that it's maximum index is [0][1]. Because i is set to the first index (in the example it would be 0), it is trying to find a number at an index that doesn't exist.

Hope this helped!
