Get StatCan correspondence data — get_tongfen_correspondence_ca

Get correspondence file for several Candian censuses on a common geography. Requires sf and cancensus package to be available

get_tongfen_correspondence_ca_census(
  geo_datasets,
  regions,
  level = "CT",
  method = "statcan",
  tolerance = 50,
  area_mismatch_cutoff = 0.1,
  quiet = FALSE,
  refresh = FALSE
)

Arguments

geo_datasets: vector of census geography dataset identifiers
regions: census region list, should be inclusive list of GeoUIDs across censuses
level: aggregation level to return data on (default is "CT")
method: tongfen method, options are "statcan" (the default), "estimate", "identifier". * "statcan" method builds up the common geography using Statistics Canada correspondence files, at this point this method only works for "DB", "DA" and "CT" levels. * "estimate" uses `estimate_tongfen_correspondence` to build up the common geography from scratch based on geographies. * "identifier" assumes regions with identical geographic identifier are identical, and builds up the the correspondence for regions with unmatched geographic identifiers.
tolerance: tolerance for `estimate_tongen_correspondence` in metres, default value is 50 metres.
area_mismatch_cutoff: discard areas returned by `estimate_tongfen_correspondence` with area mismatch (log ratio) greater than cutoff.
quiet: suppress download progress output, default is `FALSE`
refresh: optional character, refresh data cache for this call, (default `FALSE`)

Value

dataframe with the multi-census correspondence file
