us_map: Retrieve US map data

In usmap: US Maps Including Alaska and Hawaii

Retrieve US map data

Description

Retrieve US map data

Usage

us_map(
  regions = c("states", "state", "counties", "county"),
  include = c(),
  exclude = c(),
  data_year = NULL
)

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.
data_year	The year for which to obtain map data. If the value is NULL, the most recent year's data is used. If the provided year is not found from the available map data sets, the next most recent year's data is used. This can be used if an older data set is being plotted on the US map so that the data matches the map more accurately. Therefore, the provided value should match the year of the plotted data set. The default is NULL, i.e. the most recent available year is used.

Value

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