sparseLM provides an R interface to the sparseLM library for solving
nonlinear least squares problems with sparse Jacobians. The package wraps the
underlying C solver and uses CHOLMOD through the Matrix package interface,
exposing the results through an R-friendly fitting interface.
The underlying sparseLM algorithms and C library were created by Manolis
Lourakis. The R package interface was created by Colin Smith.

This package is focused on bringing sparseLM into R with:
- a wrapper for sparse Levenberg-Marquardt fitting
- support for user-supplied sparse Jacobians via
Matrixclasses
