The R package PBSddesolve generates numerical solutions for systems of delay differential equations (DDEs) and ordinary differential equations (ODEs). The numerical routines come from Simon Wood’s program 'solv95', originally written in C for the Microsoft Windows operating systems. With PBSddesolve, a user can write the gradient code for a system of DDEs or ODEs in the R language, rather than C. The code will then run on all platforms supported by R, and the results can be inspected using R’s extensive graphics capabilities. Simon has very generously given us permission to publish PBSddesolve (including his embedded routines) under the GNU GENERAL PUBLIC LICENSE Version 2.
For more information, see the User's Guide (file
PBSddesolve-UG.pdf) featured in this repository. Obtain the package PBSddesolve from CRAN (http://cran.r-project.org/), the standard repository for R contributed packages.
This package replaces an earlier R package ddesolve, which is no longer supported.
