[R-sig-Geo] species presence table weight

[Michela Giusti]

Hello everybody,

I have a question for you regarding the species presence table that I 
have to use for my ENFA analysis (sample attached).

For my analysis I have to use _numbers of colonies for square meter_. 
How can I assign a "weight" to it ??

Thank you very much for you help.
Bye,
Michela
