CGEN R Package

CGEN (Case-control.Genetics) is an R package for analyzing genetic data on case-control samples, with particular emphasis on novel methods for detecting Gene-Gene and Gene-Environment interactions.


  • The new version includes snp.score function that implements a variety of score-tests for genetic association incorporating gene-environment interactions. The function, with certain options, also allows analysis of imputed SNPs.
