  resround = "nearest",
  radius_km = EARTH_RADIUS_KM
)

Arguments

aperture: Grid aperture: 3, 4, or 7
resround: Resolution rounding: "nearest", "up", or "down"
radius_km: Radius of the body, in kilometers, or a body name such as "mars" (default Earth). See hex_grid.

# Coarse global grid (~100,000 km^2 cells)
global_grid <- hexify_grid_global(area = 100000)
plot(st_geometry(global_grid), border = "gray")
