This is an R package to perform genome-wide association studies on replicated data. It implements the EMMAX method, including cases where each genotype has more than one observation. In addition, if there are several traits it pays to analyze them together. While the GWA itself is done separately for each trait, some components of the mixed model and the SNP regression are common among traits and thus some time savings can be achieved by considering traits from the same data set together. The package is published on Zenodo.
