Ceci n’est pas un pipe.
The magrittr (to be pronounced with a sophisticated french accent) is a package with two aims: to decrease development time and to improve readability and maintainability of code. Or even shortr: to make your code smokin’ (puff puff)!
So, the answer is pipe/then (pronounced with a sophisticated french accent).
Or as @hadley & @garrett wrote:
This is my favourite form, because it focusses on verbs, not nouns. You can read this series of function compositions like it’s a set of imperative actions. Foo Foo hops, then scoops, then bops. The downside, of course, is that you need to be familiar with the pipe. If you’ve never seen %>% before, you’ll have no idea what this code does. Fortunately, most people pick up the idea very quickly, so when you share you code with others who aren’t familiar with the pipe, you can easily teach them.
The pipe works by performing a “lexical transformation”: behind the scenes, magrittr reassembles the code in the pipe to a form that works by overwriting an intermediate object.
