  I think this is a less-well-worded repeat of this question:

http://article.gmane.org/gmane.comp.lang.r.general/258611

which is not unreasonable, but no-one's gotten around to answering it 
yet.
  (Terse answer: construct a function that takes the parameters of
the ODE, and the initial conditions if you don't know them but 
estimate them at the same time, solves the ODE numerically, and
computes a goodness-of-fit score (actually a badness of fit score,
such as the sum of squares or negative log-likelihood), and use
it as the objective function in optim().)
