Description Usage Format Source References

This data was taken from Edgar Anderson's famous iris data set. This 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 Iris setosa, versicolor, and virginica. This is the target dataset (as a counterpart to the x_iris dataset) and thus only retains the Species information. As with the x_iris dataset, the data has been split into a training and test set with a ratio of 4:1. Following this the species class has been one-hot encoded to give three columns, one for each species level.

y_iris

A list of two named matrices, 'train' and 'test', representing the training and test sets for the predictors. These have 3 indicator columns each, with 120 and 30 rows respectively.

Species.setosa: Indicator column for the species class setosa
Species.versicolor: Indicator column for the species class versicolor
Species.virginica: Indicator column for the species class virginica
