-The `iris` dataset contains measures in centimeters of three different species of iris flowers [setosa, versicolor, and virginica, @becker1988new]. Imagine the following linear model in which we predict those flowers' petal width (`Petal.Width`) from the interaction between their petal length (`Petal.Length`) and their `Species`.
