There's an (experimental I think) package `odesolve'
Package: odesolve
Version: 0.5-2
Date: 2000/04/19
Title: Solvers for Ordinary Differential Equations
Author: R. Woodrow Setzer <setzer.woodrow at epa.gov>
Depends: R (>= 1.0.0)
Description: This package provides an interface for ODE solvers lsoda,
lsodar, ddassl, ddslrt. ODEs are expressed as R functions.
License: Public Domain
of which I don't have an URL ready.
------
For an ODEPACK interface, please consider interfacing to the GSL
GSL -- The GNU Scientific Library
http://sourceware.cygnus.com/gsl/
(which has a C version of odepack with it's own gsl-interface)
This would be great to have (and we could use `it' for numerical
integration, too; it has QUADPACK too...)
Both these have been on my todo list for many months, but unfortunately
never come close to the top of that list.... ;-(
