[R-sig-eco] Extract residuals from adonis function in vegan package

[Eduard Szöcs]

Dear Alicia and Jari,

just a thought:
Couldn't be capscale or betadisper be used for this?
 - To obtain the distances to the group centroid?

But than: How to convert this from distances to abundances?

Neither would they be residuals in the traditional meaning of the word as we are dealing with dissimilarities or distances, and these cannot be negative. We got to discuss this with vegan developers.
