Loading and Displaying the Dataset
\(~\)
Fisher’s measurements are one of many built-in datasets with R. These come ready to load as datasets, and below we call and print a pretty head (first six rows) of the dataset. Note that there are measurements of Petal Length, Petal Width, Sepal Length, and Sepal Width for three species; iris setosa, iris virginica, and iris versicolor.
