Function get.eigentraits [cape v2.0.2]
keywords
algebra
title
Calculate eigentraits from phenotype matrix
description
This function performs the singular value decomposition (SVD) on the phenotype matrix after first removing individuals with missing data. The eigentraits are the left singular vectors of the decomposition. This function optionally mean centers and normalizes the phenotype matrix before performing the SVD.
