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.
