st_as_sf() now returns polygons that draw correctly on flat longitude/latitude maps: cells crossing the antimeridian are split into MULTIPOLYGONs, cells containing a pole are closed along latitude ±90, and long edges follow their great circles. Spherical areas are unchanged. Use wrap = FALSE for the raw spherical polygons. Unprojected plot() displays use the same geometry, so polar cells no longer smear across the map.
Bundled DGGRID 9.03b source, compiled without GDAL at install time, so no separate DGGRID installation is needed. The package is now AGPL-3.0-or-later.
cell_cover() clips with DGGRID’s AIGEN format and applies polygon holes in R, keeping cells on islands inside holes.
Fixed automatic plot resolution failing (“No source cells are visible”) for wide regional datasets, such as North Atlantic storm tracks.
Fixed raster_to_cell() failing for rasters narrower than 60 degrees that do not cross a multiple of 60 degrees longitude.
New README with rendered examples, and three vignettes: getting started, plotting, and rasters and polygons.
Added an IGEO7/Z7-first API over DGGRID 9.x.
Added ISEA3H/Z3 selection and a partial dggridR compatibility fallback.
Added conversion, boundary, neighbor, traversal, hierarchy, sf, and polygon fill helpers with H3-like snake-case names.
Reworked cells as vctrs vectors supporting mixed resolutions.
Separated grid identity from DGGRID backend configuration.
Standardized cell operations on a cell_ grammar and type-stable relation tibbles.
Made the legacy dggridR fallback explicit and added classed cli errors.
Deduplicated point, sequence-number, relation, and geometry requests before invoking their backends while preserving the original result order.
Batched hierarchy and graph traversal work by resolution and search depth, including shared searches for repeated distance origins.
Standardized optional-package checks with rlang’s package-checking API.
Switched center extraction from GeoJSON to compact DGGRID text output and added bounded internal chunks for large point, center, boundary, and sequence-number requests.
Added delayed cli progress for hierarchy, graph traversal, distance, and polygon-cover operations without adding a runtime dependency.
Made parent lookup a local Z7/Z3 index operation, removing a DGGRID process from parent aggregation and level-of-detail selection.
Added center-only viewport selection, antimeridian handling, projection after aggregation, fixed-resolution plotting, and a lod = FALSE escape hatch.
Added 100 thousand, 1 million, and 10 million row plotting benchmarks and a naive fine-polygon comparison.
Added cell_sample() for fast center-point extraction from SpatRaster layers without cell polygons.
Added cell_extract() for exact raster-pixel coverage with area-weighted continuous defaults and categorical mode extraction.
Added raster_to_cell() with edge-cell padding, projected-raster support, and 0-to-360 longitude handling; all raster helpers return lazy globalhex_data objects.
Made full-longitude raster conversion enumerate the bounded whole DGGS instead of sending globe-spanning polygons through DGGRID’s clipper.
Added controllable cell_cover() edge densification and made long DGGRID failures safe and concise while retaining their full diagnostic text.
Made raster conversion drop all-missing cells by default and made plotting ignore missing values before LOD selection, avoiding needless downsampling for sparse global rasters.
Added render = "auto", "polygon", or "raster" plotting. Automatic mode rasterizes large display layers through optional terra, keeps explicit borders vector-based, and records the renderer on the returned data.
