abstract: Provides an R interface to the 'sparseLM' C library for large-scale nonlinear
  least squares problems with arbitrarily sparse Jacobians. The underlying solver
  implements a sparse variant of the Levenberg-Marquardt algorithm for minimizing
  sum-of-squares objective functions, supports user-supplied analytic Jacobians or
  finite-difference approximation, and is designed to exploit sparsity for improved
  memory use and performance. This package exposes the solver in R and uses sparse
  matrix classes and the 'CHOLMOD' sparse Cholesky factorization routines through
  the 'Matrix' package interface. Methods from the C library are described in Lourakis
  (2010) <https://doi.org/10.1007/978-3-642-15552-9_4>.
