The code provided here is running spatial disturbance models in a cellular automata framework. This is part of a collaborative project between the group of Sonia Kéfi (Institut de Sciences d'Evolution, CNRS, IRD, Université Montpellier, France) and Vishwesha Guttal (Center for Ecological Sciences, Indian Institute of Science, Bangalore, India).
The R-package is build around objects of a particular class
ca_model (S3 objects in R) that contain all the model specific information, like the original publication, the update functions, and the cell states.
These objects can be handled by a function called
ca() which runs the cellular automata over time.
Other functions allow the plotting of single snapshots or timeseries, the generation of initial lattices/grids/landscapes, the calculation of spatial and temporal indicators as provided by the package 'spatialwarnings'.

Contribute to the package
Just a couple of guidelines for contributing code to the package:
- The collaborative work on the package is coordinated via the issues. No uninvited pull-requests, please! Before you start developing a feature, please create an issue and assign yourself (if it does not exist yet).
- Clone the repository to your computer and work locally. If you add a new function or modify an existing one please include a valid documentation using roxygen2. If you refer to functions of other packages, put them in the
Importlist in DESCRIPTION and use the structure
package::function()to apply them in the code.
- Before you push your commits to GitHub, please be sure that everything works fine by testing the new functionality on your local repository. Test functions that rely on your function, too! If your feature works, create a last commit where you increase the version number in
0.0.1and mention the related issue in your commit message, e.g.
git commit -m "transfer code into R-package #1". If you're not listed yet, add your name to the
