in the vignette for
SNPRelate, under PCA, the plot is labeled as x="eigenvector 2" and y="eigenvector 1". My knowloedge on PCA is very basic and I was wondering if this is the same as x="PC2" and y="PC1".
Similarly, I want to also ask if the element
$eigenvect in the
pca object created by the function
snpgdsPCA correspond to the loadings for each SNP.
As I said, my knowledge on PCA is very basic (I am working on it though) and apologize for this basic question.
