Dear list members, sorry for cross posting but I didn?t get a solution from
the R-sig-ecology,

When working with adehabitatHR after fitting a kernel I got the following
erro message that I don?'t understand:

kud <- kernelUD(analisisUtm[,5], h="href")
kud

********** Utilization distribution of several Animals ************

Type: probability density
Smoothing parameter estimated with a  href smoothing parameter
This object is a list with one component per animal.
Each component is an object of class estUD
See estUD-class for more information

class(kud)

[1] "estUDm"

ver <- getverticeshr(kud, percent=95)

Error: identicalCRS(x, y) is not TRUE

because of a change in sp and in R, adehabitatHR had to change from
using the deprecated overlay() to using over(), and this led to a change
in getverticeshr(). In contrast to overlay(), over() checks that both
its arguments have identical CRS, which was not the case here.

@Clement: I guess that in getverticeshr.r, line 42, the
SpatialPolygons() call needs to pass on the CRS as second argument named
"proj4string". You might want to check the other occasions of changes
from overlay() into over().

Best,

Manuel
