brain_polygons format
(ggseg.formats 0.0.3). The atlases now render without sf and its
GDAL/GEOS/PROJ system libraries, enabling wasm and air-gapped installs.
Plots are unchanged.All 20 Schaefer atlas objects (schaefer7_100 through schaefer7_1000 and
schaefer17_100 through schaefer17_1000) are now ggseg_atlas objects
(from ggseg.formats) containing both 2D and 3D data. The separate _3d
objects have been removed.
Use ggplot() + ggseg::geom_brain(atlas = schaefer7_400) for 2D plots and
ggseg3d::ggseg3d(atlas = schaefer7_400) for 3D plots -- both from the same
object.
ggseg.formats is now a hard dependency (in Depends).
