write_disk(gn_file))
}
gn <- read_delim(gn_file,
delim = "\t",
col_names = c("geonameid",
"name",
"asciiname",
"alternatenames",
"latitude",
"longitude",
"feature_class",
"feature_code",
"country_code",
"cc2",
"admin1_code",
"admin2_code",
"admin3_code",
"admin4_code",
"population",
"elevation",
"dem",
"timezone",
"modification_date"))
bad <- gn |>
filter(str_detect(feature_code, "^PPL"),
str_detect(asciiname, "\\b[Bb]ad\\b"))
bad |>
leaflet() |>
