esp_get_gridmap: Get a sf hexbin or squared polygon of Spain

Description

Loads a hexbin map (sf object) or a map of squares with the boundaries of the provinces or autonomous communities of Spain.

Usage

esp_get_hex_prov(prov = NULL)
esp_get_hex_ccaa(ccaa = NULL)
esp_get_grid_prov(prov = NULL)
esp_get_grid_ccaa(ccaa = NULL)

Arguments

prov

A vector of names and/or codes for provinces or NULL to get all the provinces. See Details.

ccaa

A vector of names and/or codes for autonomous communities or NULL to get all the autonomous communities. See Details.

Value

A sf POLYGON object.

Details

Hexbin or grid map has an advantage over usual choropleth maps. In choropleths, a large polygon data looks more emphasized just because of its size, what introduces a bias. Here with hexbin, each region is represented equally dismissing the bias.

You can use and mix names, ISO codes, "codauto"/"cpro" codes (see esp_codelist) and NUTS codes of different levels.

When using a code corresponding of a higher level (e.g. esp_get_prov("Andalucia")) all the corresponding units of that level are provided (in this case , all the provinces of Andalucia).

Results are provided in EPSG:4258, use sf::st_transform() to change the projection.
