R help - Feb 2013 - AUC from ENFA model

Dear all,



I am currently running an ENFA in R using Adehabitat pkg to assess species
distribution and I am really stuck and need some help to finalize my
project.

I run the ENFA in both original location data and pseudo-absence points
(the latter randomly generated using dismo pkg), and now I would like to
assess the performance of the ENFA, however, I am not sure about how to
tackle this. I did not understand how to extract the prediction values from
each output  to generate the AUC/ROC.

Please, could anyone give me a hand with that?

Thank you very much,



Leandro
