class ROptimx(RPackage):
"""Expanded Replacement and Extension of the 'optim' Function:
Provides a replacement and extension of the optim() function to call to
several function minimization codes in R in a single statement. These
methods handle smooth, possibly box constrained functions of several or
many parameters. Note that function 'optimr()' was prepared to simplify the
incorporation of minimization codes going forward. Also implements some
utility codes and some extra solvers, including safeguarded Newton methods.
Many methods previously separate are now included here. This is the version
for CRAN."""
