During April 2025, Mine Cetinkaya-Rundel contributed to tidyverse.org and duckplyr by developing educational content and enhancing documentation. She authored a blog post demonstrating how AI tools can support learning the tidyverse in R, providing practical examples in data reshaping, plotting, and web scraping, and offering guidance on prompt engineering and code validation. In the duckplyr repository, she improved documentation by clarifying memory handling for large datasets and adding examples for unsupported operations, such as group_by and rowwise. Her work, primarily using R, Markdown, and technical writing, improved onboarding and reduced user confusion through clear, actionable educational resources and documentation.
