[R] Vegan R^2 and tau values for metaMDS

Dimensionality doesn't matter. 2, 3, 14 will all work.

What matters is that apparently vegan returns the results in some
format other than a straight sites x ordination coordinates matrix,
which is what dist expects. You'll need to convert it to one, possibly
with as.matrix, or extract the coordinates component from a
list, or whatever is appropriate for the output of that function from
that package. The help file should tell you the correct approach
for getting the nmds configuration itself.
