Identification and Visualisation of European NUTS Regions from Geolocations
Assemble all-levels output (0..3) with status from level 3
Assemble single-level output
Build map data (frequencies, splits, and an auto-zoom extent)
Convert numeric lat/lon vectors to sf POINT (WGS84)
Country filter by CNTR_CODE (if available)
Cached Eurostat geospatial layer
Spatial join + optional nearest fallback (robust; km units)
Compact message printer
Pre-filter polygons by bounding box of points (safe with fallback)
Render the map (ggplot2)
Normalise get_nuts() output for mapping
Parameter validation for get_nuts()
Identify NUTS Regions for Geolocations
Plot NUTS Matches on a Map
Provides functions to identify European NUTS (Nomenclature of Territorial Units for Statistics) regions for geographic coordinates (latitude/longitude) using Eurostat geospatial boundaries. Includes map-based visualisation of the matched regions for validation and exploration. Designed for regional data analysis, reproducible workflows, and integration with common geospatial R packages.
