   FFoorrmmaatt::

        `iris' is a data frame with 150 cases (rows) and 5
        variables (columns) named `Sepal.Length',
        `Sepal.Width', `Petal.Length', `Petal.Width', and
        `Species'.

        `iris3' gives the same data arranged as a 3-dimensional
        array of size 50 by 4 by 3, as represented by S-PLUS.
        The first dimension gives the case number within the
        species subsample, the second the measurements with
        names `Sepal L.', `Sepal W.', `Petal L.', and `Petal
        W.', and the third the species.

        This famous (Fisher's or Anderson's) iris data set
        gives the measurements in centimeters of the variables
        sepal length and width and petal length and width,
        respectively, for 50 flowers from each of 3 species of
        iris.  The species are Setosa, Versicolor, and Vir-
        ginica.
