factorize

If variables within a data frame are not factors, try to
 convert them. Not intended for end-user use; this is
 a utility function that needs to be exported, for technical reasons.

models

utilities

Fit linear and generalized linear mixed-effects models.
The models and their components are represented using S4 classes and
methods.  The core computational algorithms are implemented using the
'Eigen' C++ library for numerical linear algebra and 'RcppEigen' "glue".
