This is a compendium of example data and code designed to help end users explore the crawl package for analysis of animal movement from telemetry data.
The crawl package is an R package that provides analytical tools for
estimating the movement paths of animals from telemetry data. The package is
specifically designed with marine mammals in mind, but other species in other
habits with similar telemetry devices will work. This package compendium
provides step-by-step instructions for importing and setting up the telemetry
data, initiating the crwMLE(), crwPredict(), and crwSimulator()/'crwPostIS() functions and visualizing results. The write up
also discusses use of the fix_path() function to re-route predicted tracks
around land. Examples of data visualization plots are also presented. This
compendium was originaly developed in support of a training course at the NOAA
Fisheries Protected Species Assessment Workshop in La Jolla, California, USA.
You can install the released version of crwexampleakbs from GitHub with:
install.packages("devtools")
