What’s New in R: May 13, 2024
Welcome to this week’s edition of What’s New in R! This week, we’re featuring a Quarto extension to show when your document was most recently updated, animations of common functions, and a video to show you how to efficiently import hundreds of Excel files to R. Let’s dive in!
Add last rendered or modified time to Quarto
Say you’re working on an analysis in a Quarto document and you want to add a timestamp to show when it was last updated. How would you do this? You could write some code, of course. Or you can use now, a Quarto extension made by Garrick Aden-Buie, which makes this process as simple as adding the code {{< now >}}.
Visualizing {dplyr}’s mutate(), summarize(), group_by(), and ungroup() with animations
For people just starting out, remembering what R functions do can be a challenge. Andrew Heiss has given us a great collection of animations to demonstrate some of the most common functions from the {dplyr} package.
Read hundreds of Excel files into one dataset with one line of code
Did you know that you can use just one line of code to read hundreds of Excel files into R? In this video, Samer Hijjazi shows you how. And note: this same technique works with CSV (or any other format) files as well!
