Overview

About

Maintained by Michael J GraylingCRAN page ↗GitHub ↗

Performs a qualitative analysis of one- and two-dimensional autonomous ordinary differential equation systems, using phase plane methods. Programs are available to identify and classify equilibrium points, plot the direction field, and plot trajectories for multiple initial conditions. In the one-dimensional case, a program is also available to plot the phase portrait. Whilst in the two-dimensional case, programs are additionally available to plot nullclines and stable/unstable manifolds of saddle points. Many example systems are provided for the user. For further details can be found in Grayling (2014) doi:10.32614/RJ-2014-023.

Install

R (source archive)pak (dev)

url <- "https://cran.r-project.org/src/contrib/Archive/phaseR/phaseR_2.2.1.tar.gz"
pkgFile <- "phaseR_2.2.1.tar.gz"
download.file(url, pkgFile)
install.packages(pkgFile, type = "source", repos = NULL)

This package is no longer on CRAN, so install.packages() cannot fetch it by name. This downloads the last archived source (2.2.1) and builds it locally. Install its dependencies first, and note that building from source needs the usual compiler toolchain.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("mjg211/phaseR")

Development version from mjg211/phaseR. Installs pak first if it is not already available.
