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".

This approach builds the package from source, i.e.
make and compilers must be installed on your system -- see the R FAQ for your operating system; you may also need to install dependencies manually. Specify
