I don't know if it was meant to be this way, because it's actually not weird to say `data time` but assuming it was meant to be `date time` I amended:
regular data time `lubridate::as_date_time()` -> regular date time `lubridate::as_date_time()`
According to the output and documentation, `.drop` was deprecated as an argument. I'd propose just removing this chunk and adding a comment in the original `unnest(glance)` pipeline
We can include levels with no observations in dplyr::count() now with the .drop = FALSE argument setting. I changed the wording and added an example. Please feel free to amend text wording and remove example if you wish.
In transform.Rmd (Chapter 5, Data Transformation), under Counts (5.6.3),
we removed na.rm = TRUE when computing mean because all NAs for
arr_delay were already removed when creating not_cancelled dataset.
