Add normalized name columns to boundaries — mn_boundaries

Adds a name_std column to an sf boundary object by transliterating, lowercasing, and stripping special characters from place names. This enables reliable joins between NSO data and administrative boundary polygons.

Usage

mn_boundaries_normalize(g, name_col = "shapeName")

Arguments

g: sf object from mn_boundaries().
name_col: Column with English names (default 'shapeName').

Value

An sf object with an additional name_std column.

Examples

aimags <- mn_boundaries("ADM1")
aimags <- mn_boundaries_normalize(aimags)
head(aimags$name_std)
#> [1] "uvs"         "khovd"       "zavkhan"     "bulgan"      "dornogovi"  
#> [6] "ulaanbaatar"
