What’s New in R: October 13, 2025
Welcome to this week’s edition of What’s New in R! This week, we’re featuring a guide to removing or hiding legends in {ggplot2}, Posit’s AI newsletter update, and a tutorial on creating time-aware isochrones for accessibility mapping. Let’s dive in!
Remove or Hide Legends in ggplot2 – Theme, Guides, Scales
This practical tutorial demonstrates how to remove or hide legends in {ggplot2} plots, covering both complete legend removal and selective legend management for plots with multiple layers. The post shows various approaches using theme settings, the guides() function, and scale modifications. It’s a handy reference for those common situations where you need fine-grained control over which legends to display, especially useful when working with complex multi-layered visualizations.
Posit AI Newsletter
Sara Altman and Simon Couch from Posit share their latest AI newsletter, providing updates on the rapidly evolving world of artificial intelligence tools for data science. The newsletter highlights recent developments including Positron Assistant and DataBot, two AI-powered tools built into Positron that aim to enhance data analysis workflows. This is an excellent resource for staying current with AI developments in the R and Python ecosystems, particularly if you’re interested in exploring these new AI-assisted coding features.
Time-aware isochrones for accessibility mapping with R and Mapbox tools
Kyle Walker demonstrates how to create time-aware isochrones in R using Mapbox tools for accessibility mapping. Isochrones show areas reachable within specific time intervals, and this tutorial covers both static and interactive mapping approaches. Walker explains practical applications for urban planning, transportation analysis, and accessibility studies, making this a valuable resource for anyone working with spatial data and interested in understanding travel time patterns and accessibility analysis.
