%description
Extremely efficient procedures for fitting the entire group lasso and
group elastic net regularization path for GLMs, multinomial, the Cox model
and multi-task Gaussian models. Similar to the R package glmnet in scope
of models, and in computational speed.  This package provides R bindings
to the C++ code underlying the corresponding Python package 'adelie'.
These bindings offer a general purpose group elastic net solver, a wide
range of matrix classes that can exploit special structure to allow
large-scale inputs, and an assortment of generalized linear model classes
for fitting various types of data. The package includes The package is an
implementation of Yang, J. and Hastie, T. (2024)
