The deSolve and phaseR packages for numerical resolution of Ordinary Differential Equations with R Los paquetes deSolve y phaseR para la resolución numérica de Ecuaciones Diferenciales Ordinarias con R

Abstract

In the R language, specific packages have been developed that enable the numerical treatment of initial value problems for equations and systems of differential equations. In particular, the deSolve package allows, among others, the numerical and graphical solution of initial value problems for ordinary differential equations and the phaseR package the qualitative analysis of Autonomous Systems of ordinary differential equations, in a and two dimensions. The purpose of this article is to illustrate the use of the deSolve package with a modification of the logistic equation and Chen’s system and the phaseR package with a model that generalizes Hooke’s law.
