Dear all,
I have strong interest on Ecological Niche Model, which in general use a set
of environmental variables (continuous, categorical etc) and Presence (or
Presense/Absence) records for species. I think that "grasp" and "adehabitat"
packages could help me on these tasks.
My input layers are on ASC format, and the record of species is a data-frame
with X, Y, name of species. Note that in general we don´t have real absence
data.

Could someone give some advice how can I use "grasp" and/or "adehabitat" to
generate my predictive models?

Best regards,
