Home range overlap indices implemented using kernel density estimators with plug-in smoothing parameters and Program R

This collection contains R code to implement the home range overlap indices evaluated by Fieberg and Kochanny (2005). These indices have been incorporated into the adehabitat package of Program R. However, the adehabitat package does not currently (as of April 2014) allow calculation of home ranges using the 'plug-in' method for choosing smoothing parameters when estimating home ranges using kernel density estimates. In addition, the code here allows one to use two separate smoothing parameters rather than a single parameter (as in the current version of adehabitat). An illustrative example is included that makes use wild boar location data contained in the adehabitat package. For references, see README.txt.
