[R] solving first-order differential equation

[Johannes Ranke]

The fourth-order Runge-Kutta method is in the odesolve package on CRAN, 
but they manual says, only for didactial purposes. First order
differential equations are generally conveniently solved by the 
lsoda function in this package. I hope this helps, even if it does not
directly answer your question.

Best regards,

Johannes Ranke
