hal9001 R package: The scalable Highly Adaptive Lasso

Routines for constructing sparse matrices of basis functions, as well as a custom implementation of L1-regularized regression (i.e. the LASSO), altogether providing a fast, computationally efficient implementation of the Highly Adaptive LASSO (HAL), primarily in C++ but made available for use in R through Rcpp.
