Package: epistasisGA 1.15.0

Michael Nodzenski

epistasisGA: An R package to identify multi-snp effects in nuclear family studies using the GADGETS method

This package runs the GADGETS method to identify epistatic effects in nuclear family studies. It also provides functions for permutation-based inference and graphical visualization of the results.
