This is an adaptation of the iris dataset (embedded in the
"datasets" R-package) to the needs of the BiPlotteR functions (i.e.
Biplot 3D, Biplot 2D and Scatterplot).
You have to follow the same structure when building your input data frame.
data("Iris_4BPLTR")
A data frame with six columns.
This column offers a number codification for the
iris samples; elements in this column will appear as point annotations in
the biplot when using the Biplot 3D and Biplot 2D functions.
This column contains a-priori information about your samples; in this particular case, plant samples are grouped according to their species. Points referred to samples that have the same value in the second column of the dataset (the name of the species in this case) will be displayed with the same color in the biplot
The sepal length measured for each plant sample
The sepal width measured for each plant sample
The petal length measured for each plant sample
The petal width measured for each plant sample
