Pooya TaherkhaniandGitHub 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.

nattalidesandGitHub 84f0ba1ba7 one_of() is retired (#867) 
Further to {tidyselect} documentation "one_of() is retired in favour of the more precise any_of() and all_of() selectors." this exercise (5.4.1) should be updated to be in-line with current functionality.

DSGeoffandHadley Wickham d1a63fe379 Minor typos (#689) 
* Fix a few minor typos

Examples include saying we'll learn about filter() in the next chapter, but it's not until chapter 5.  And, also, it says we'll learn about how to use multiple geoms in the same plot in the next section, but then not far below, in the same section, it shows how to use multiple geoms.

* Three minor fixes in chapter 5

* Remove " I introduced in prior commit
