Get European coordinates

Loads and returns names, id, and coordinates for European countries, to use with mapping functions and other "map" functions that accept an sf object.

Usage

loadCoordEU(unit = c("nuts0", "nuts1", "nuts2", "nuts3", "urau"),
            year = c("2021","2016", "2013", "2010", "2006", "2003"),
            scale = c("20", "60"), unit_subset = NULL,
            matchWith = NULL, dir = NULL,
            use_cache = TRUE, use_internet = TRUE, crs = NULL)

Arguments

unit: the type of European statistical unit to link
year: year of the analysis
scale: the scale of the map
unit_subset: character vector of unit names to extract
matchWith: the type of id
dir: local directory in which shape files are stored
use_cache: a logical value indicating whether to use the cache
use_internet: a logical value indicating wheter the coordinates are downloaded from https://github.com/mappinguniverse/geospatial. If FALSE the maps downloaded during package installation will be used
crs: coordinate reference system. Look at st_crs

Details

Coordinates are download from the Github repo https://github.com/mappinguniverse/geospatial from EU folder https://github.com/mappinguniverse/geospatial/tree/master/EU.

If unit is not specified, borders of the European countries are loaded.

Value

A data.frame object with columns indicating names, ids, iso and the geometries to map.
