Reproject the points to the coordinate system of thr grid, do the overlay
then copy the attributes back. No need to warp a raster just for over(lay).

adehabitatHR. I've clipped my area and saved as an ASC file from ArcGIS.
The kernelkc help says the parameter should be of class asc. I've read it in
as both an asc and a SpatialGridDataFrame, but get an error from

Precisely. You should use great-circle distances with lat-lon
coordinates, rather than Euclidean distance, because the actual length
varies with position on the globe.
Converting to UTM or something similar is one solution if your points
are not too far apart.
There are many other R solutions: se
Dear list,
I am using the package geoRglm to do some predictive mapping. There is a
function that calculates the distance between observed data points and the
prediction locations using a .C call to a function which eventually calculates
the length of the hypotenuse between one location and the

Hello,
I'm not able to use the crop function for a raster Stack. I read that this
problem was corrected in the CRAN version v 2.0-08.
But it still not working for me also I modified the CRAN.
Can somebody advise me.
