Minor issue at https://r4ds.hadley.nz/logicals#sec-numeric-summaries-of-logicals. The explanation and variable name for proportion_delayed seems to be backwards from what is calculated, as it's giving the proportion of flights with less than 60 minute delay. Should probably be renamed proportion_ontime.
