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, each year in the data frame is processed separately.

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")
pop20_nonauto <- detect_adm2_type(pop20, mode = "non")
pop20_auto <- detect_adm2_type(pop20, mode = "atn")
unique(pop20_nonauto$adm2_code)
