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()`
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.
