vanderlindenma 2ee3426457
str_view(), repetition at most n times yields error #807, and small typos in "Iteration chapter" (#808) 
* Update and rename strings.Rmd to strings.Rmd 

Proposed fix related to this issue: https://github.com/hadley/r4ds/issues/807

A more comprehensive fix should perhaps discuss why "`{,m}`: at most m" does not work (or warn the reader that it does not)

* Typos in iteration.Rmd

Correcting two small typos

* Add missing word

* Add code example for 1,m

hadley 92d7665920 Drop handling hierarchy 
It's just a bit too raw - and rather than polishing it, it would be better to put the time in to (e.g.) ggplot2 scales
