%description
Fits hierarchical regularized regression models to incorporate potentially
informative external data, Weaver and Lewinger (2019)
<doi:10.21105/joss.01761>. Utilizes coordinate descent to efficiently fit
regularized regression models both with and without external information
with the most common penalties used in practice (i.e. ridge, lasso,
elastic net). Support for standard R matrices, sparse matrices and
big.matrix objects.
