Worked on improving documentation for the tidyverse/duckplyr repository, focusing on the funnel.Rmd vignette to address user confusion regarding funnel behavior and dplyr fallbacks. Used R Markdown to clarify that fallbacks to dplyr are not possible for funneled frames, ensuring the documentation accurately reflects the package’s functionality. Fixed a grammar issue and corrected an erroneous argument, which enhanced the clarity and usability of the vignette. This work reduced potential support questions by aligning user guidance with actual software behavior. The primary technical skills applied were documentation writing and R Markdown, with attention to detail and user experience throughout the process.
