Nothing
Provides tools for working with nonlinear least squares problems. It is intended to eventually supersede the 'nls()' function in the R distribution. For example, 'nls()' specifically does NOT deal with small or zero residual problems as its GaussNewton method frequently stops with 'singular gradient' messages. 'nlsr' is based on the nowdeprecated package 'nlmrt', and has refactored functions and Rlanguage symbolic derivative features.
