[R] nonlinear equation solver?

[Wang, Zhu]

Thanks to all.
 
I know how to solve it numerically but I am just wondering if there is a function already in R or S. I guess I have to implement some C codes then.
 
Thanks to Murray for good observation.
 
I am not sure why optim function is working in general to solve a nonlinear equation from Patrick's advice.
