%description
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.
