What’s New in R: September 15, 2025
Welcome to this week’s edition of What’s New in R! This week, we’re featuring a comprehensive guide to working with colors in R, a keynote on using AI to augment data workflows, and a package for creating diagrams with ggplot2. Let’s dive in!
Working with colours in R
Nicola Rennie provides a comprehensive guide to working with colors in R, covering everything from basic color specification methods like hex values and RGB to more advanced topics. The post explores various approaches to accessing and manipulating colors, discusses packages for creating color-blind friendly palettes, and demonstrates how to build custom color schemes. It’s an excellent resource for anyone looking to improve their data visualization skills and make their plots more accessible and visually appealing.
I wrote this talk with an LLM
In this keynote presentation from useR! 2025, Hadley Wickham explores how AI can augment rather than replace data science workflows. As the Chief Scientist at Posit and creator of the tidyverse, Wickham shares insights on the evolving relationship between humans and AI in data analysis. The talk demonstrates practical ways that large language models can enhance productivity while maintaining the critical thinking and domain expertise that data scientists bring to their work.
{ggdiagram}
The {ggdiagram} package, developed by W. Joel Schneider, takes an object-oriented approach to creating diagrams using ggplot2. This package makes it easy to create flowcharts, organizational charts, and other types of diagrams directly in R. With support for various shapes, arrows, and layout options, {ggdiagram} provides a powerful alternative to external diagramming tools while keeping everything within the R ecosystem and maintaining the flexibility of ggplot2.
