Note

penguins is a great introductory data set used throughout the data science and machine learning community (all the variables are exogenous; penguins can't choose their measurements!). To make things a bit easier, all rows with NAs were removed (to avoid issues like passing na.rm = TRUE to summary routines like mean() and so on).
