Control the Iterations in nls

Description

Allow the user to set some characteristics of the nls nonlinear least squares algorithm.

Usage

nls.control(maxiter=50, tol=1e-05, minFactor=1/1024)

Arguments

maxiter A positive integer specifying the maximum number of iterations allowed.
tol A positive numeric value specifying the tolerance level for the relative offset convergence criterion.
minFactor A positive numeric value specifying the minimum step-size factor allowed on any step in the iteration. The increment is calculated with a Gauss-Newton algorithm and successively halved until the residual sum of squares has been decreased or until the step-size factor has been reduced below this limit.

Value

A list with exactly three components:

maxiter
tol
minFactor
