Description

This GPS dataset contains the locations of 10 Eastern grey kangaroos Macropus giganteus monitored between 05/01/2010 to 21/12/2011 in South East Queensland, Australia. Data supplied E.C. Best from the School of Biological Sciences, University of Queensland, Australia.

Usage

data(Roos)

Format

A data frame containing GPS location data of individual sightings of M. giganteus with the following 3 variables.

ID

a character vector giving the identity of each kangaroo

x

a numeric vector containing the x coordinate of each individual

y

## Plot observed location data with individual kangaroos by colour
plot(Roos,col='red')

## Estimation of UD for the 10 kangaroos
ud <- kernelUD(Roos, same4all=TRUE)

## Plot the UD for the 10 kangaroos
