The pleior package provides tools for identifying and analyzing pleiotropic genetic variants in genome-wide association studies (GWAS). It includes functions for data loading, preprocessing, pleiotropy detection, and visualization, enabling researchers to explore shared genetic mechanisms across complex traits.
