In bsmity13/LoCoHverlap: Estimate animal range overlap using LoCoh and EMD

LoCoHverlap

LoCoHverlap (pronounced “Loke - Overlap”) is an R package to compare animal range overlaps using Local Convex Hull (LoCoH) home range estimators and Earth Mover’s Distance (EMD). It streamlines the following workflow: 1. Fit LoCoH home ranges to sets of animal locations. 2. Convert fitted LoCoHs to utilization distributions (UD) estimated on a raster. 3. Measure overlap using the continuous metric EMD.

A full description of this method and its use in animal ecology is currently in prep.

Installation

You can install the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("bsmity13/LoCoHverlap")

Current Status

This package is in the early stages of development and is not yet functional. The currently planned updates are:

• [x] Basic workflow
  • [x] Basic function to fit 1 LoCoH
  • [x] Basic function to rasterize 1 LoCoH
  • [x] Basic function to calculate EMD between any number of LoCoHs
• [ ] Seasonal overlap workflow
  • [ ] Iterate basic workflow over individuals in a season
  • [ ] Compare individuals within a season
  • [ ] Compare an individual across seasons
• [x] Moving window workflow
  • [x] Use moving window to compare consecutive ranges of an individual along a track
• [x] Simulated example data to be used in help files and vignettes
• [ ] Vignette for each workflow
  • [ ] Basic
  • [ ] Seasonal
  • [ ] Moving window
• [ ] Parallelize workflow

This README will be updated as new functionality comes online or workflow is revised.
