R help - Sep 2001 - Using a zero-finding routine in R

Hello all!

I'd like to use a routine in R to find the zero of a function (like
Newton-Raphson, Broyden, etc.)
In the  manual, I found a reference to Newton-Raphson method in the
"qr" function, but I simply wonder how I could use it to implement
such a
method.

Have a look at uniroot(), or optim() for more complex tasks.
