phaseR-package: Phase Plane Analysis of One and Two Dimensional Autonomous...

Description Details Author(s)


phaseR is an R package for the qualitative analysis of one and two dimensional autonomous ODE 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, additionally programs are available to plot nullclines and stable/unstable manifolds of saddle points. Many example systems are provided for the user.

The package contains nine main functions for performing phase plane analysis:

In addition, the package contains over 25 derivative functions for example systems. Links to these can be found in the packages index.

An accompanying guide with further information, examples, and exercises, can be found in the doc directory of the packages installation.

This package makes use of the ode function in the package deSolve.
