Description: Tools for multivariate data analysis. Several methods are
        provided for the analysis (i.e., ordination) of one-table
        (e.g., principal component analysis, correspondence analysis),
        two-table (e.g., coinertia analysis, redundancy analysis),
        three-table (e.g., RLQ analysis) and K-table (e.g., STATIS,
        multiple coinertia analysis). The philosophy of the package is
        described in Dray and Dufour (2007)
        <doi:10.18637/jss.v022.i04>.
