pcadapt

R package {pcadapt} has been 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: A new paper is finally out describing version 4 of pcadapt (which has been available for quite some time now). Please cite the new paper.
