Hello all, 
Thing is like that now I have 14 sampling sites with the species and environment data. Which analysis is the best choice for determining the difference/dissimilarity among those sites. I have installed the R (2.12.2 version), which soft package or function should I take to achieve my objective.
Thanks very much for your time and suggestion.
Best Regards
Yong

Hai Yong,
have a look at the vegan package: with the function vegdist() you can 
calculate dissimilarity indices.
There are also some good tutorials on vegan available on the net.
HTH,
Eduard
