Match addr_street vectors

Source: R/addr_part_match.R
match_addr_street.Rd

A single addr_street in y is chosen for each addr_street in x. If exact matches (using as.character) are not found, possible matches are chosen by fuzzy matching on street name (using phonetic street key and street name) and exact matching on the enabled street components. Ordinal street names use restricted phonetic candidates: an ordinal phonetic key like #0007 may fuzzy match only to plausible ordinal neighbors such as digit shifts (#0070, #0700, #7000) or same-width substitutions (#0008, #0009), not arbitrary OSA-distance-one ordinal keys such as #0017 or #0077. Ties are broken by .......... the first for now.

addr_street objects within missing or empty @name are not matched and returned as missing instead.

Usage

match_addr_street(
  x,
  y,
  name_phonetic_dist = 1L,
  name_fuzzy_dist = 2L,
  match_street_predirectional = TRUE,
  match_street_posttype = TRUE,
  match_street_pretype = TRUE,
  match_street_postdirectional = FALSE
)

Arguments

x, y

addr_street vectors to match

name_phonetic_dist

integer; maximum optimized string alignment distance between phonetic_street_key() of x and y to consider a possible match

name_fuzzy_dist

integer; maximum optimized string alignment distance between @name of x and y to consider a possible match

match_street_predirectional

logical; require street predirectional to match when selecting street candidates?

match_street_posttype

logical; require street posttype to match when selecting street candidates?

match_street_pretype

logical; require street pretype to match when selecting street candidates?

match_street_postdirectional

logical; require street postdirectional to match when selecting street candidates?

Value

an addr_street vector, the same length as x, that is the best match in y for each addr_street code in x; if no best match is found a missing value is returned (addr_street())
