I'm sure there's a simpler way to do this using the labels of the
distance matrix, but I can't see it. I've thought of converting it
using as.matrix(), which would allow me to pull out particular rows,
but I'm only interested in the triangluar matrix. Now, if there was a
way to as.matrix(dmat) such that I got the bottom triangular matrix
and zeros elsewhere, then I'd be in buisness. Any suggestions on how
to pull that off would be helpful.
I'm certainly interested in any tips or tricks anyone might have for
working with distance...
