In biodray/QuickPop: Tools to work around population genetics analyses

Description

Compute variance explained by a few PCA axis

Usage

pca_scoretable(x, naxe = 1)

Arguments

x	glPCA object
naxe	number of axis for which you want to extract PCA scores

Details

PCA from glPca. It will return a dataframe, including ID and pca.score for the desire number of axis

Examples

## simulate a toy dataset
x <- adegenet::glSim(50,4e3, 50, ploidy=2)
## perform PCA
pca1 <- adegenet::glPca(x, nf=3)
## Extract variance
res <- pca_scoretable(pca1, naxe=3)
head(res)
