An R-package to boost fitness and life expectancy of environmental models

Ordinary differential equations (ODE) are at the center of many environmental models. The R software is increasingly used to implement ODE-based models boosted by add-on packages providing numerical solvers. This paper introduces an R package called rodeo to facilitate the implementation of ODE-based models. It addresses a standardized model notation and documentation as well as the automatic generation of efficient, solver-compliant Fortran or R source code. The package has the potential to make a multitude of environmental models, more comprehensible, reusable, and exchangeable.
