Normalise postal codes — normalise

Some special postcodes are used in addresses, such as codes for post office boxes. This helper converts those to the postcode for the closest normal suburb if there is a reasonable clear match. If there is no good match, the postcodes are left unchanged.

Usage

normalise_postcodes(codes)

Arguments

codes: Character vector of postcodes (or coercible to one).

Value

Character vector of the same size as the input, but with the normalised postcodes.

Details

Note that this goes a little further than the aliases that are registered with cartographer (which only account for postcodes with no geospatial data in the ABS dataset).

Examples

normalise_postcodes(c(1685, 2000, 1010, 2129, 2145))
#> [1] "2114" "2000" "2000" "2140" "2145"
