Equal-area world tile grid

A statebins-style equal-area tile grid of the world (one square per country) so tiny states are actually visible. Uses the bundled world_tiles layout. For small multiples of a tile grid, facet the result as you would any other ggplot (or see facet_map() for the choropleth equivalent).

Usage

tile_map(data, fill, label = TRUE, footnote = "auto")

Arguments

data

A country-level frame with iso3c and the fill column.

fill

The fill column (unquoted).

label

Whether to draw ISO codes on the tiles (default TRUE).

footnote

The caption, as in world_map(): "auto" (default) states the coverage and source, a string is used as given, FALSE adds nothing.

Value

A ggplot object.

Details

Every tile in the layout is drawn, taking the scale's na.value fill where data has no row for it. The converse also holds and is quieter: data rows keyed on one of the 3 countries with no tile are dropped without a warning (see world_tiles for which).

Backend

Drawn on the bundled equal-area tile grid (world_tiles), one square per country; no geometry backend is involved.

Examples

# \donttest{
tile_map(countryatlas::world_snapshot$countries, gdp_per_capita)
