Description: A 'ggplot2' based implementation of biplots, giving a
        representation of a dataset in a two dimensional space
        accounting for the greatest variance, together with variable
        vectors showing how the data variables relate to this space. It
        provides a replacement for stats::biplot(), but with many
        enhancements to control the analysis and graphical display. It
        implements biplot and scree plot methods which can be used with
        the results of prcomp(), princomp(), FactoMineR::PCA(),
        ade4::dudi.pca() or MASS::lda() and can be customized using
        'ggplot2' techniques.
