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

[stephen sefick]

I am using the function metaMDS with jaccard distances to ordinate a
set of constituent by site matrix.  I can post this data if it would
be helpful, but it is large to include in an email.  I can also
provide reproducable code if necessary.  I would like to get an R^2
value for the axes of the ordination configuration that I get with
metaMDS in the vegan package is there a way to do this- is it stored
in some object returned by the function that I am unaware of- or is
there another function inside of vegan or elsewhere- that I can use?
I have seen mention of ecodist function nmds having an R^2 would this
be the place to go?

so little or so large that all they really do for us is puff us up and
make us feel like gods. We are mammals, and have not exhausted the
annoying little problems of being mammals.
