[R-sig-Geo] Help with ENFA in R

[Alexandre Villers]

Hi,

Typing ?enfa (after loading adehabitatHS) and searching through the 
examples that are provided, you should find these lines

## We prepare the data for the ENFA
tab <- slot(map, "data")
pr <- slot(count.points(locs, map), "data")[,1]

Maybe you could start with this, i.e. understanding how the pr object is 
obtained, playing with the example.
And then, if you really don't get it, ask someone on the list to help you.
