R package {pcadapt} was developed to detect genetic markers involved in biological adaptation. This package uses statistical tools for outlier detection based on Principal Component Analysis (PCA).
A tutorial for {pcadapt} is available on pcadapt's website.
News: Our paper describing version 4 of pcadapt (which has been available for quite some time now) is out. Please cite the newest paper (see Refs below).
