Spread and gather

[gadenbuie]

kierisi: there's a pretty large discrepancy between how well I think I know spread() and gather() and how well I actually know spread() and gather() 😬

Yup this is exactly the intuition I developed! Really helps to think of have and want. Only addition I might propose is if I want to gather all but one column you can just do gather (data,wantkey,wantval, -column that shouldn't be gathered)

Me guessing if gather() or spread() is the right choice. Literally every time I need it. #rstats #tidyverse

Spread and gather as in spreading butter on bread and gathering leaves into a pile: https://twitter.com/WeAreRLadies/status/1054742083607642112

I can't remember the difference between spread() and gather() to save my life. So I decided to rename them instead 😂🤓

also worth giving historical context against reshape2 based functions e.g. melt/cast, and/or dare I suggest even older aggregate style solutions with reshape for us dinosaurs?
