%description
Extend lasso and elastic-net model fitting for ultra high-dimensional,
multi-gigabyte data sets that cannot be loaded into memory. Designed to be
more memory- and computation-efficient than existing lasso-fitting
packages like 'glmnet' and 'ncvreg', thus allowing the user to analyze big
data analysis even on an ordinary laptop.
