devPTIpack

devPTIpack is an R package for building interactive, geo-spatial Project Targeting Index (PTI) dashboards using Shiny. Given administrative boundary shapefiles and a metadata workbook of socioeconomic indicators, it computes weighted composite scores across admin levels and serves them in a ready-to-deploy Shiny application — no front-end coding required.
