Usage

atlas_geometry_type(atlas)

is_atlas_sf(atlas)

is_atlas_polygon(atlas)

Arguments

atlas

a ggseg_atlas object

atlas_geometry_type() returns "sf" or "polygon", and errors if the atlas has no recognised 2D geometry. is_atlas_sf() / is_atlas_polygon() return a logical scalar (FALSE for non-atlases).

Examples

atlas_geometry_type(dk())
#> [1] "polygon"
is_atlas_polygon(dk())
#> [1] TRUE
