us_map: Retrieve US map data

In usmapdata: Mapping Data for 'usmap' Package

Retrieve US map data

Description

Retrieve US map data

Usage

us_map(
  regions = c("states", "state", "counties", "county"),
  include = c(),
  exclude = c(),
  as_sf = TRUE
)

Arguments

regions	The region breakdown for the map, can be one of ("states", "state", "counties", "county"). The default is "states".
include	The regions to include in the resulting map. If regions is "states"/"state", the value can be either a state name, abbreviation or FIPS code. For counties, the FIPS must be provided as there can be multiple counties with the same name. If states are provided in the county map, only counties in the included states will be returned.
exclude	The regions to exclude in the resulting map. If regions is "states"/"state", the value can be either a state name, abbreviation or FIPS code. For counties, the FIPS must be provided as there can be multiple counties with the same name. The regions listed in the include parameter are applied first and the exclude regions are then removed from the resulting map. Any excluded regions not present in the included regions will be ignored.
as_sf	Defunct, this parameter no longer has any effect and will be removed in the future.

Value

An sf data frame of US map coordinates divided by the desired regions.

Examples

str(us_map())

df <- us_map(regions = "counties")
west_coast <- us_map(include = c("CA", "OR", "WA"))

excl_west_coast <- us_map(exclude = c("CA", "OR", "WA"))
