Detect adm2 type from adm2_code field then return the exact codes

adm2_code often refers to the codes of autonomous _Gu_s or non-autonomous _Gu_s. The head table of the data frame may contain either or both of the two types of codes. This function detects the type of the codes in the adm2_code field and returns the exact codes accordingly.

Usage

detect_adm2_type(df, year = NULL, mode = "non", adm2_code = "adm2_code")

Arguments

df: A head data frame containing the full dataset. i.e., censuskor
year: The year for which to filter the data. If not specified, the function will use the data.frame as is.
mode: A character vector of "atn" (autonomous) and "non" (non-autonomous).
adm2_code: A character vector of adm2_code field Default is "adm2_code".

Value

filtered data frame with exact codes

Examples

# Load 2020 census population
pop20 <- anycensus(year = 2020, type = "population")
#> Using character codes that are convertible to integers. Automatically converting to integers...
pop20_nonauto <- detect_adm2_type(pop20, mode = "non")
pop20_auto <- detect_adm2_type(pop20, mode = "atn")
unique(pop20_nonauto$adm2_code)
