Katherine Lai developed and maintained the UCD-SERG/serocalculator R package, focusing on robust API design, data management, and visualization workflows. Over five months, she delivered a comprehensive refactor that consolidated external data sources, modernized the API, and improved test coverage and documentation. Using R, R Markdown, and ggplot2, Katherine implemented new plotting frameworks, streamlined function naming, and enhanced package hygiene for CRAN compliance. Her work included deprecating legacy interfaces, expanding unit tests, and refining vignettes to support reproducible analytics. The result was a maintainable, well-documented codebase that improved usability, reliability, and release readiness for epidemiological data analysis.

Jan 1, 2025January 2025 performance for UCD-SERG/serocalculator focused on data source consolidation, packaging hygiene, test stability, and release readiness. Key deliverables include migrating from OSF-driven external data to built-in package datasets, moving files to extdata and converting to CSV/RDS, with corresponding load-function updates to remove OSF references. Packaging, documentation, and CRAN-readiness were enhanced through versioning, NEWS updates, and documentation improvements, including CRAN-compliant notes and guidance. The test suite was strengthened by migrating to test datasets, updating tests and snapshots, and re-enabling donttest/dontrun where appropriate. The codebase was cleaned of OSF references and unnecessary data-raw artifacts, and an internal API exposure pathway via ::: was added to support internal usage/tests. The removal of any::metaplus dependency simplified the dependency surface. A successful CRAN submission was tracked and reflected in the release workflow. These efforts improved reproducibility, reliability, and maintainability, and position the package for smoother future releases.
