[R-sig-dyn-mod] Using dynamically compiled code for use with deSolve in a new package

[Thomas Petzoldt]

Hi,

that's straightforward.

1) Put deSolve in Depends of your package DESCRIPTION:

Depends: deSolve


2) Import the solver function (e.g. ode or lsoda) in the NAMESPACE of 
your package and declare your dynamic library (.dll or .so)

importFrom(deSolve,ode)

useDynLib(mypackage)


3) and then use this .dll/.so in the call to ode():

ode(...., dllname = "mypackage", .....)


An example can be found in package growthrates:

Hope it helps,

Thomas
