cairo vs dggridR
A side-by-side editorial comparison of cairo and dggridR — release velocity, themes, recent moves, and the top alternatives to consider.
cairo vs dggridR: at a glance
What is cairo?
Cairo finally catches R's graphics engine, all the way to GE API 16.
Cairo is the R device that renders plots through the cairo library, and until 1.7-0 it lagged R's own graphics engine by several API generations. That release closes the gap to GE API 16 (R 4.5.0), adding fill patterns, masks and groups. The releases before it were maintenance: a segfault shim for grid, a bashism removal in configure, and Windows font and build fixes.
What is dggridR?
A discrete global grid generator grew cell traversal and became a usable spatial index.
dggridR builds discrete global grids — icosahedral tessellations of the Earth into equal-area hexagonal or triangular cells — by wrapping the DGGRID C++ engine. The 4.1.0 release adds dgneighbors, dgchildren and dgparent for moving between adjacent cells and across resolutions, plus dgpoints_to_cells and dgbin_points for mapping and aggregating point data into cells. New aperture 7 and mixed-aperture ISEA43H grid types arrive alongside them.

Cairo finally catches R's graphics engine, all the way to GE API 16.
◆ Current state
Cairo is the R device that renders plots through the cairo library, and until 1.7-0 it lagged R's own graphics engine by several API generations. That release closes the gap to GE API 16 (R 4.5.0), adding fill patterns, masks and groups. The releases before it were maintenance: a segfault shim for grid, a bashism removal in configure, and Windows font and build fixes.
◆ Where it's heading
The arc is catch-up, executed one API generation at a time. Glyph rendering arrived in 1.6-3, GE 15 stubs in 1.6-5 existed only to stop grid from segfaulting, and 1.7-0 delivers the real GE 13/14/16 feature set rather than placeholders. Alongside that, dropping the CAIROGD_VER C API and the mkdist step means the package now builds with plain R CMD build, which reads as deliberate reduction of maintenance overhead.
◆ Prediction
Expect the next releases to be corrective rather than additive: the entries show every API adoption here has been followed by a fix release, and patterns, masks and groups are a much larger surface than glyphs were.

A discrete global grid generator grew cell traversal and became a usable spatial index.
◆ Current state
dggridR builds discrete global grids — icosahedral tessellations of the Earth into equal-area hexagonal or triangular cells — by wrapping the DGGRID C++ engine. The 4.1.0 release adds dgneighbors, dgchildren and dgparent for moving between adjacent cells and across resolutions, plus dgpoints_to_cells and dgbin_points for mapping and aggregating point data into cells. New aperture 7 and mixed-aperture ISEA43H grid types arrive alongside them.
◆ Where it's heading
The package changed hands in effect as well as in code: the 4.0.0 engine update to DGGRID v9.0b and the first real test suite were contributed by Sebastian Krantz, who also maintains the upstream engine fork, and 4.1.0's feature burst followed two weeks later. The direction of that burst is unmistakable — away from generating grids for plotting and toward using them as an indexing structure that point data gets binned into and navigated through.
◆ Prediction
Expect the cell hierarchy functions to extend to non-hexagonal apertures and multi-level traversal, closing the remaining gaps against established global indexing systems.
