Dear Christian,
I would like to perform some ecological niche factor analysis (ENFA) using the adehabitat package and am not too sure about the location data. Basically I have them as longitudes and latitudes at the moment but I could also generate then as 'tile index' (e.g. lower left corner has the latitude -90 and longitude -180 so the 'tile index' would be 0, 0 - right?). Which is the correct location data format?
The location data should be in the same coordinate system as the maps. Therefore, the locations should be expressed as longitude/latitudes.
