Routines for fitting kinetic models with one or more state variables to chemical degradation data CRAN Task View: DifferentialEquations (http://CRAN.R-project.org/view=DifferentialEquations) Calculation routines based on the FOCUS Kinetics Report (2006). Includes a function for conveniently defining differential equation models, model solution based on eigenvalues if possible or using numerical solvers and a choice of the optimisation methods made available by the FME package (default is a Levenberg-Marquardt variant). Please note that no warranty is implied for correctness of results or fitness for a particular purpose.
