deSolve (version 1.2-3)

rkInternal: Internal Functions for the Runge-Kutta Family of ODE Solvers.

Description

These are the internal workhorses of rk, which are normally not intended to be called by the end user. Though internal, both functions are visible in the user's workspace to allow for easy inspection and fine-tuning of the algorithms by experienced users.

Usage

rkFixed(y, times, func, parms, tcrit = NULL, verbose = FALSE, hini = 0,
  method = rkMethod("rk4", ...), ...)

rkAuto(y, times, func, parms, rtol = 1e-06, atol = 1e-06,
  tcrit = NULL, verbose = FALSE, hmin = 0, hmax = NULL, hini = 0,
  method = rkMethod("rk45dp7", ...), maxsteps = 5000, ...)

Details

Arguments and value are described in the manual page of the top-level function rk. Note that rkFixed is used for methods with fixed time step and rkAuto for embedded methods with automatic step size determination. Both functions return raw values of the integration without external interpolation and without the "global" return values of the model.
