get_tongfen_ca_census {tongfen}

Togfen data from several Canadian censuses

Description

Get data from several Candian censuses on a common geography. Requires sf and cancensus package to be available

Usage

get_tongfen_ca_census(
  regions,
  meta,
  level = "CT",
  method = "statcan",
  base_geo = NULL,
  na.rm = FALSE,
  tolerance = 50,
  area_mismatch_cutoff = 0.1,
  quiet = FALSE,
  refresh = FALSE,
  crs = NULL,
  data_transform = function(d) d
)

Arguments

regions

census region list, should be inclusive list of GeoUIDs across censuses

meta

metadata for the census veraiables to aggregate, for example as returned by meta_for_ca_census_vectors.

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.

base_geo

base census year to build up common geography from, 'NULL' (the default) to not return any geographi data

na.rm

logical, determines how NA values should be treated when aggregating variables

tolerance

tolerance for 'estimate_tongen_correspondence' in metres, default value is 50 metres, only used when method is 'estimate' or 'identifier'

area_mismatch_cutoff

discard areas returned by 'estimate_tongfen_correspondence' with area mismatch (log ratio) greater than cutoff, only used when method is 'estimate' or 'identifier'

quiet

suppress download progress output, default is 'FALSE'

refresh

optional character, refresh data cache for this call, (default 'FALSE')

crs

optional CRS to transform data to, and use for spatial intersections if method is 'identifier' or 'estimate'

data_transform

optional transform function to be applied to census data after being returned from cancensus

Value

dataframe with variables on common geography
