Compute a dynamic solution with the numerical algorithms from package
deSolve.
The matrix returned by the integrator (see ode).
Times of interest (numeric vector).
Switch between compiled Fortran and R code (logical). Default
is TRUE.
Assign names to output columns holding the process rates?
Default is TRUE.
Auxiliary arguments passed to ode.
See notes below.
Use step for integration over a single time step
with a built-in, Fortran-based solver.
