Add an NA hspanicr column if one doesn't exist

Hispanic origin was not recorded until 1989. In order to keep all dataframes conformable, add an NA column named hspanicr if one does not exist.

Usage

add_hspanicr_column(icd_df)

Arguments

icd_df

an MCOD dataframe)

Value

dataframe

See also

add_hispanic_origin, which adds the binary hispanic_origin column (for population joins) derived from hspanicr; this function only backfills the raw hspanicr field.

Examples

df <- data.frame(year = 2019, ucod = "X42")
add_hspanicr_column(df)
#>   year ucod hspanicr
#> 1 2019  X42       NA
