🎉🐱  purrr-tiest cheat sheet

Purrr royal decree (ok, I’ll stop with the 🐱  puns now), the purrr 📦  now has its very own official RStudio cheat sheet: Apply Functions Cheat Sheet

The purrr package makes it easy to work with lists and functions. This cheatsheet will remind you how to manipulate lists with purrr as well as how to apply functions iteratively to each element of a list or vector. The back of the cheatsheet explains how to work with list-columns. With list columns, you can use a simple data frame to organize any collection of objects in R.

So, I thought we’d celebrate with a bit of a purrr 🐦  tweet roundup:

This is a far cry from an exhaustive collection. If you’ve written something you think belongs here, send me a tweet 🐦  (@dataandme), or leave a comment. Blogging isn’t exactly the best format for updated lists, but I’m hoping to cook up a better method soon!
