Map PSGC codes to a target release

Usage

map_psgc(code, from = "auto", to = latest_release())

Arguments

code: A character vector of 10-digit PSGC codes.
from: Release the codes come from, or `"auto"` (default) to detect automatically using the earliest release that contains each code.
to: Target release name. Defaults to [latest_release()].

Value

A data frame with columns `old_code`, `new_code` (`NA` for abolished codes), `mapping_type` (`"direct"`, `"renumbered"`, `"split"`, `"merged"`, or `"abolished"`), `from_release`, and `to_release`. Split codes produce multiple rows.

Examples

map_psgc("0100000000")
#>              old_code   new_code mapping_type from_release to_release
#> 0100000000 0100000000 0100000000       direct      Q1_2023    Q1_2026
map_psgc(c("0100000000", "0102800000"), to = "Q4_2023")
#>              old_code   new_code mapping_type from_release to_release
#> 0100000000 0100000000 0100000000       direct      Q1_2023    Q4_2023
#> 0102800000 0102800000 0102800000       direct      Q1_2023    Q4_2023
