Nothing
The nls.lm function provides an R interface to lmder and lmdif from the MINPACK library, for solving nonlinear leastsquares problems by a modification of the LevenbergMarquardt algorithm, with support for lower and upper parameter bounds. The implementation can be used via nlslike calls using the nlsLM function.
