Dear Moses,

There is a very nice new package to calculate home ranges: rhr

It is described in the paper of Signer and Balkenhol: Reproducible home 
ranges (/rhr/): A new, user-friendly R package for analyses of wildlife 
telemetry data
An easy example how to use the package to calculate kernel home ranges 
could be found here:|http://jmsigner.github.io/rhrman/cliHRE.html
|You can choose to use the LSCV estimate of h in the command (|rhrHlscv).
The home range needs to be estimated for each individual (only if you 
would like to look at the area used by your population you could 
calculate one single home range).
Maybe you could do this in a loop, subsetting the data for one 
individual and calculate the home range.

Best wishes,

I cannot get the right figure that will be used in all the movement data I have. It looks like I need to estimated for each animal monitored. How can I get a common figure? I have 30 data sets and creating 30 LSCV by continuous trial seems not the clever way of doing it. Please help.
