描述

The tidyr package provides a framework for creating and shaping tidy data, the data format that works the most seamlessly with R and the tidyverse. The front page of this cheatsheet provides an overview of tibbles and reshaping tidy data. The back page provides an overview of creating, reshaping, and transforming nested data and list-columns with tidyr, tibble, and dplyr. With list-columns, you can use a simple data frame to organize any collection of objects in R. Updated August 2021.

This two-page cheatsheet is divided into tiblles, reshaping data, expanding tables, handling missing values, and nested data.
