bifurcationEWS

bifurcationEWS is an R package accompanying the paper “Early Warning Signals of Complex Critical Transitions in Deterministic Dynamics” by Evers et al. (submitted to Nonlinear Dynamics). The package supports timeseries simulation of many deterministic bifurcations, computation of some univariate and multivariate Early Warning Signals (EWS), and an assessment of the performance of EWS. As an example, it uses the four-dimensional Generalised Lotka-Volterra (GLV) model, with strength of interconnectivity $s$ as the control parameter.

These transitions can also be visualised using a bifurcation diagram:

Installation

You can install bifurcationEWS with:

# install.packages("devtools")
devtools::install_github("KCEvers/bifurcationEWS")
library(bifurcationEWS)

See the vignette for a demonstration on how to use the package. Note that the code will need heavy editing if used for any other purpose that reproducing the results of the paper.
