lsmnsd is an R package that analyzes animal movement using latent-state model and net squared displacement.
This is the development area for the package
lsmnsd, which provides a series of functions to analyze and classify animal movement strategies based on analysis of Net Squared Displacement (NSD) and latent-state model.

Installation of the development version
You need to use the package
devtoolsfrom Hadley Wickham.
You also need a version of JAGS and the package
R2jags installed before using the package.
The package main functions are
classify. The package comes with movement data from two giant tortoises : Christian and Zelfa. For a list of documented functions see the Reference manual.
Alternatively, here is a quick example to get you going:
library(lsmnsd) data(Christian) nsd1<-NSD_fct(Christian$x, Christian$y) Christian_out<-clustNSD(cbind(range01(nsd1), Christian$Time), n.iter=10000, WAIC=F, simplify=F) summary(simple.clust(Christian_out)) Christian_class<-classify(Christian_out) summary(Christian_class)
