Find a single root of a function of one variable within a specified interval.
1 
fn 
A real function of a single variable. 
gr 
A function that computes the gradient of 
x0 
An initial guess for the value of the root of 
offset 
An inverse tolerance for the root. When a new estimate of the root 
maxiter 
A limit on the number of function evaluations permitted in the attempt to find a root. 
trace 
If TRUE, provided diagnostic output of the process of rootfinding. 
... 
Extra data needed to compute the function 
To be added.
The output is a list consisting of return(list(root=b, froot=NA, rtol=wtol, maxit=maxit)) ## Acceptable approx. is found */
root 
The estimate, b, of the position of the root. 
froot 
The value of the function at this point, f(b). 
rtol 
The width of the interval in which the root exists. 
fcount 
The number of function evaluations used.
