46c395a954 Potential typo? (#897) 
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()`

9d6ed46c5e Removed reference to deprecated .drop argument (#896) 
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

e2d5d7b31a Switch from stat() to after_stat() in chap 3. (#895) 
The docs in of aes_eval in [most recent](https://ggplot2.tidyverse.org/reference/aes_eval.html?q=after%20_%20stat#arguments) ggplot2 3.3.2 say that after_stat() and after_scale() has replaced stat().

23996a081d dplyr does have a drop option (#894) 
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.

164172d32a Drop na.rm=TRUE when data is already purged of NAs (#811) 
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.
