Learn R Programming

⚠️There's a newer version (1.1-37) of this package.Take me there.

lme4 (version 1.1-18-1)

Linear Mixed-Effects Models using 'Eigen' and S4

Description

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".
