Shiny Apps

Interactive R Shiny projects by Federica Gazzelloni: Oregon Frogs, pathogen data, word prediction, and historical COVID-19 applications.

Interactive applications from my R programming and analytical work. These earlier projects explore spatial data, health metrics, and language models.

Apps open in a separate tab and may take a moment to start. The previews show their initial screens; older applications may rely on services or packages that have changed since development.
