Are there any cheat sheets of stringi available? Like this one of stringr: http://edrub.in/CheatSheets/cheatSheetStringr.pdf

It would be more efficient to have a cheat sheet since R base, stringr, and stringi have different but similar types of syntax, which could be confusing some times.

Add a few useful date/time types from time (https://hackage.haskell.org/package/time) , e.g.

• POSIXTime
• Date
  etc.

A checklist for where to add things :

• prim constructors go in here : https://github.com/ocramz/heidi/blob/master/src/Data/Generics/Encode/Internal/Prim.hs#L25
• Heidi instances go here : https://github.com/ocramz/heidi/blob/master/src/Data/Generics
