Learn R Programming

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

lme4 (version 1.0-5)

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".
