The ultimate R data.table cheat sheet

Speed. Concise syntax. Backwards compatibility.

But especially speed.

Those are some of the features that make R’s data.table compelling to its fans.

And even if you’re a confirmed tidyverse user (as I am), data.table can be a useful addition to your R toolkit — especially when working with large data sets, in a Shiny app, or in a package function. 

This R data.table ultimate cheat sheet is different from many others because it’s interactive. You can search for a specific phrase like add column or by a type of task group such as Subset or Reshape. In addition, because this cheat sheet includes tidyverse “translation” code, you can also search for a favorite dplyr verb such as mutate or rowwise.

Registered InfoWorld users can download an expanded version of this interactive table for use on their own systems! Registration is free.
