What’s New in R: September 2, 2025
Welcome to this week’s edition of What’s New in R! This week, we’re featuring a practical guide to the {fs} package for file management, a reusable Quarto template from the USGS Water Data team, and a tutorial on using R to explore data related to long COVID. Let’s dive in!
File Management With The {fs} Package
Albert Rapp shows how the {fs} package streamlines file and folder operations in R. He covers common tasks like creating directories, listing and filtering paths, copying/moving files, and using path helpers that play nicely across operating systems.
Duplicating Quarto elements with code templates to reduce copy and paste errors
The USGS Water Data team offers a quick demo showing how to use child documents in Quarto (or R Markdown) to create templates that can be reused. In their work, they need to create summaries for multiple analyses. Rather than copying and pasting code, they iterate, creating a child document that they then duplicate across all analyses.
Visible vs. invisible in R
Athanasia Mowinckel has written a very interesting blog post showing how she analyzes data from the Visible app to track her progress dealing with long COVID. It’s a nice example of how to use R to do foundational data analysis and visualization.
