get species within sites ordihull polys
Dear Tim, Sound's like your looking for indicator species ? Maybe the indicspecies packages suites your needs. Dufr?ne, M and P. Legendre. 1997. Species assemblages and indicator species: the need for a flexible assymetrical approach. Ecological Monographs 67: 345 - 366. De C?ceres, M., P. Legendre, and M. Moretti, 2010. Improving indicator species analysis by combining groups of sites. Oikos 119: 1674 -1684. Cheers, Eduard

This isn't the best example because species points don't fall in more than one of the black polygons. But, my question: Can I easily identify which blue points (species) fall within the polygon? Or can I easily identify which species are 'most important' (most abundant?) for defining each of the three groups? Thanks for any pointers Tim Howard
