Installation:

Most of the requirements of snpnet are available from CRAN. It also depends on the pgenlibr, glmnet/glmnetPlus and cindex (for survival analysis) packages. One can install them by running the following commands in R. Notice that the installation of pgenlibr requires zstd(>=1.4.4). It can be built from source or simply available from conda, pip or brew.

library(devtools)
install_github("junyangq/glmnetPlus")
install_github("chrchang/plink-ng", subdir="/2.0/cindex")
install_github("chrchang/plink-ng", subdir="/2.0/pgenlibr")

We assume the users already have PLINK 2.0. Otherwise it can be installed from https://www.cog-genomics.org/plink/2.0/.
