Optimisation methods

I don't want to re-invent the wheel, and I'm trying to code up something
that does a Nelder-Mead simplex method to minimise a non-linear objective
function.  (I'm porting something I originally wrote in matlab, using the 
optimisation toolbox funciton fmins).

Is there already something available to do this included in R?

Yes. help(optim).
