nlsrk provides to nls(stats) an evaluation of functions defined by first order Ordinary Differential Equations (ODEs). For a single ODE use
frunge and edit
dfdt. For a system of ODEs, use the multivariate functions
evrunge and edit
sys. The method used in both cases is the Runge-Kutta 4 method. The result is not guaranteed especially for "stiff" systems of equations.
