  long_offset = 0, lat_offset = 0, exclude = character())

Arguments

d	Numeric. Number between 0 and 1. Procentwise Diameter (length from center to corner) of the tiles.
center	Logical. When TRUE returns the center coordinates of the tile map.
style	Character. Selets the layout style of the tile map.
size	Numeric. Size of the tiles.

  geom_map(aes(fill = Murder), map = states_map) +
  expand_limits(x = states_map$long, y = states_map$lat)

states_map <- hex_usa(d = 0.5)

ggplot(crimes, aes(map_id = state)) +
  geom_map(aes(fill = Murder), map = states_map) +
  expand_limits(x = states_map$long, y = states_map$lat) +
