R help - Aug 2002 - Numerical Optimization

Hi,

Is there a function, or package, in R that does numerical optimisations,
such as the Newton-Raphson method?

I searched through the help files and found the "optim" function, but
it
does seem like it has this N-R method.

Cheers,

Kevin

Right, it has better ones.  nlm() has a modified Newton method, though.
