[R-sig-eco] Which analysis should I take?

[Yong Zhang]

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
