get_tongfen_correspondence_ca_census {tongfen}

Get StatCan correspondence data

Description

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

Usage

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
