List all child variables from vector hierarchies given either a list of Census variables returned by list_census_vectors, search_census_vectors, find_census_vectors, or a direct string reference to the vector code.

Source: R/census_vectors.R

List all child variables from vector hierarchies given either a list of Census variables returned by list_census_vectors, search_census_vectors, find_census_vectors, or a direct string reference to the vector code.

child_census_vectors(
  vector_list,
  leaves_only = FALSE,
  max_level = NA,
  keep_parent = FALSE
)

Arguments

vector_list

the list of vectors to be used, either a character vector or a filtered tibble as returned from list_census_vectors.

leaves_only

boolean flag to indicate if only final leaf vectors should be returned, i.e. terminal vectors that themselves do not have children.

max_level

optional, maximum depth to look for child vectors. Default is NA and will return all child census vectors.

keep_parent

optional, also return parent vector in list of results. Default is set to FALSE.

Examples

# Query parent vectors directly using vector identifier
child_census_vectors("v_CA16_2510")
#> # A tibble: 4 × 7
#>   vector      type  label             units  parent_vector aggregation details  
#>   <chr>       <fct> <chr>             <fct>  <chr>         <chr>       <chr>    
#> 1 v_CA16_2513 Total 0 to 17 years     Number v_CA16_2510   Additive    CA 2016 …
#> 2 v_CA16_2519 Total 18 to 64 years    Number v_CA16_2510   Additive    CA 2016 …
#> 3 v_CA16_2522 Total 65 years and over Number v_CA16_2510   Additive    CA 2016 …
#> 4 v_CA16_2516 Total 0 to 5 years      Number v_CA16_2513   Additive    CA 2016 …
