Macro invertebrate Enumeration with Shiny, R
summary
Automates freshwater and marine macro‑invertebrate enumeration that used to be done by hand in Excel, replacing cut‑and‑paste and fiddly formulas with a Shiny app in R that accepts CSV input from field IDs, looks up scores from Stark and Winterbourn references, and batches samples. It returns MCI and Shannon index calculations (hard and soft bottom MCI, diversity, evenness), supports multiple samples, exports results to Excel, and is hosted on GitHub — it works reliably and saves time.
