[R] how to use optim() or nlm() to solve three nonlinear equations

[Nai-Wei Chen]

Dear all,

I just know how to solve an eaquation by using optim() or nlm(). But, now, I 
have three nonlinear equations, 
how could we use optim() or nlm() to solve  a system of nonlinear equations in 
R?  Thank you so much.


Sincerely,

Joe
