[fixed] vectorized nested loop: apply a function that takes two rows
(Extremely sorry, disregard previous email as I hit send before pasting the latest version of the example; this one is smaller too)

I want to apply a function that takes two vectors as input to all pairs
(combinations (nrow(X), 2))of matrix rows in a matrix.
I know that ideally, one should avoid loops in R, but after reading the docs for
do.call, apply, etc, I still don't know
