Overview

About

Maintained by Woody MiaoFirst published 2025-07-255 releasesCRAN page ↗

Provides a comprehensive suite of genome-wide association study (GWAS) methods specifically designed for biobank-scale data, including but not limited to, robust approaches for time-to-event traits (Li et al., 2025 doi:10.1038/s43588-025-00864-z) and ordinal categorical traits (Bi et al., 2021 doi:10.1016/j.ajhg.2021.03.019). The package also offers general frameworks for GWAS of any trait type (Bi et al., 2020 doi:10.1016/j.ajhg.2020.06.003), while accounting for sample relatedness (Xu et al., 2025 doi:10.1038/s41467-025-56669-1) or population structure (Ma et al., 2025 doi:10.1186/s13059-025-03827-9). By accurately approximating score statistic distributions using saddlepoint approximation (SPA), these methods can effectively control type I error rates for rare variants and in the presence of unbalanced phenotype distributions. Additionally, the package includes functions for simulating genotype and phenotype data to support research and method development.

Install

R (CRAN)Ubuntu (r2u)Fedora (COPR)

install.packages("GRAB", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-grab

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-GRAB

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager
