Create paint by numbers images

The 'paintr' GitHub repository hosts an R package for creating paint-by-numbers images. It leverages the 'magick' package for image processing and color picking, and 'sf' and 'rmapshaper' packages for handling image polygons. Users can apply noise reduction, smoothing, and polygon simplification to adjust the image feel. It also allows for custom color palettes. The repository contains examples, including usage with Hadley Wickham's photo, demonstrating how to generate a paint-by-numbers result and apply different palettes for the desired artistic effect.

Create Sankey and Alluvial Diagrams Using ggplot2 • ggsankeyfier

The ggsankeyfier package enhances ggplot2 by allowing the creation of Sankey and Alluvial diagrams, which are types of data visualization that depict the flow of quantities through stages or categories. It provides specialized functions to handle the complex layout of these diagrams, including the ability to model skipped stages or feedback loops. The package defines its own terms for consistency and offers a thesaurus for commonly used Sankey terminology. It can be installed from CRAN or GitHub and is integrated into the ggplot2 workflow, requiring structured data for plotting.

Creating template files with R

Nicola Rennie's blog post teaches readers how to save time when dealing with repetitive tasks by creating template files with R. The post explains fine-tuning R scripts for tasks like #TidyTuesday, where similar sections are involved each week. Instead of copying and pasting scripts and GitHub README files weekly and updating parts manually, Rennie introduces a method for generating template files and folders based on a date argument. This process includes creating organized directories and template files, replete with content placeholders, which can then be customized for the specific week's work.
