Learn what a data frame looks like when printed, and identify its variables and their types. We’re going to use the mpg and flights datasets frequently, so you’ll start by familiarising yourself with them.

NB: When we need to be specific about which package a dataset or function comes from, we write it like package_name::function_name. mpg and flights come from the ggplot2 and nycflights13 packages respectively, so when we want to be explicit we’ll write ggplot2::mpg and nycflights13::flights.
