Description

Differential equations can be used to describe exchanges of matter, energy, information or any other quantities as they vary in time and/or space.

We invite you to experience how nicely and flexibly R can be used to explore time-dependend behavior of dynamical systems, that occur in any field of science: mathematics, natural and life sciences, economics, finance and engineering.

Details

We will give an overview over the different solver functions available in packages deSolve and rootSolve. Practical examples will show that even numerically challenging systems can be efficiently solved in R and how external data can be handled. An outlook will demonstrate how partial differential equations (PDE) for reaction diffusion systems in 1D, 2D or 3D can be handled in R and how impressive computation performance can be approached.

Required Software

Downloads and Preparatory Material

The guided web exercises are made with InkScape and work best with Mozilla or Chrome.

Pre-conference discussion is possible on the mailig list: r-sig-dynamic-models@r-project.org
