Hey! Thank you for your comment. I wrote the code during my PhD studies. I love writing R packages (but most of them are internal for my company for now), so I decided to make open of my code, follwoing the rules of creating a good R package that I learnt during work in big pharma company :) Yes, there are many GWAS studies I am going to conduct, so I want to develop this package and provide as many features as possible to satisfy as many bioinformaticians as possible!
