[R-sig-Geo] fpt function in adehbaitatLT

[Benjamin.Galuardi]

Hi Anna,

I have not used the fpt function per se, but my experience with LTRAJ 
objects is that adehabitat functions are designed to run across all 
individuals in the object list. The fpt example in the package:

data(puechcirc)
i <- fpt(puechcirc, seq(300,1000, length=30))
plot(i, scale = 500, warn = FALSE)

uses an object with 3 individuals.

Cheers,

Ben
