"Search" on the left under "www.r-project.org" provide 5 different

discussion of this issue, Subj: "Re: [R] Two or more dimensional root
(Zero) finding".
Hope this helps.

Hey guys, i have a relatively simple problem.
I need to use netwon's method to find the root of a polynomial, lets say
x^3-2x-1
i start off with
p <- function(x) x^3-2*x-1
My method, which im sure is very amateur, is to type another function, which is
the derivative of p, and after picking an initial value to start off with, i
follow the steps of newton's method manually, but i dont think that is what the
question is asking.
I've done some research on wikipedia, but i cant seem to find any code that
will help me.
Can someone help?
Thanks a lot
