Create comune to CPI lookup table

Source: R/utils_geographic.R
create_comune_cpi_lookup.Rd

Creates a lookup table mapping each comune to its corresponding CPI (Centro Per l'Impiego). The function performs spatial join using sf::st_join to assign each comune centroid to the CPI polygon it falls within. Falls back to existing cpi column in comuni data if spatial join fails or produces NA values.

Usage

create_comune_cpi_lookup()

Value

A data.table with columns:

  • comune_code: PRO_COM_T code for the comune (6 digits with leading zero)

  • comune_name: Name of the comune (COMUNE field)

  • cpi_code: Unique code for the CPI (cpi field)

  • cpi_name: Name of the CPI area (denominazione field)

Details

The function handles edge cases including:

  • Comuni outside CPI boundaries (uses existing cpi column)

  • Comuni on boundary lines (assigns to largest overlapping CPI)

  • Missing values (uses existing cpi column as fallback)

Examples

lookup <- create_comune_cpi_lookup()
#> Loading spatial data...
#> Error in Sys.getenv("SHARED_DATA_DIR", default = "~/Documents/funzioni/shared_data"): unused argument (default = "~/Documents/funzioni/shared_data")
head(lookup)
#> Error: object 'lookup' not found
