[R] Help with applying a function to all possible 2x2 submatrices

I apologize if the term "submatrix" was confusing - I am basically 2 rows and
2 columns from a r x c matrix to construct 2x2 matricies. Thus, the
choose(r,2) * choose(c,2) possible combinations.
For each matrix [(a,b), (c,d)], I am testing a > b, b > d, d > c, and c > a.
For the sake of simplicity I have combined these tests into a single
function (with the intent of applying it to the matrix, ideally).
I hope this is clearer...
