Installation

devtools::install_github("jedalong/wildlifeTG")

Quick demo

Calculate a quick PPA home range and compare with points:

library(wildlifeTG)

data(m3)                      #Caribou tracking data

#PPA home range
hr1 <- dynppa(m3)
hr2 <- dynppa(m3,method='vanderWatt')
plot(hr1)
plot(hr2,border='blue',add=T)

library(adehabitatLT)
points(ld(m3)$x,ld(m3)$y)

plot of chunk unnamed-chunk-2

#plot(spt,add=T,col='red')
