cairo vs distributional
A side-by-side editorial comparison of cairo and distributional — release velocity, themes, recent moves, and the top alternatives to consider.
cairo vs distributional: 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 distributional?
distributional taught + and - to work on any pair of distributions, closing the algebra it started with.
The R package providing vectorised distribution objects — the substrate that forecasting and anomaly tooling in the same ecosystem builds on. Cadence has picked up sharply, with four releases in the six months to June 2026 against roughly one a year before that. Two kinds of work alternate: adding distribution families (Dirichlet, Horseshoe, Laplace, multivariate t, g-and-k, the extreme-value pair) and deepening what can be computed generically across all of 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.
distributional
0.0ANALYTICS
distributional taught + and - to work on any pair of distributions, closing the algebra it started with.
◆ Current state
The R package providing vectorised distribution objects — the substrate that forecasting and anomaly tooling in the same ecosystem builds on. Cadence has picked up sharply, with four releases in the six months to June 2026 against roughly one a year before that. Two kinds of work alternate: adding distribution families (Dirichlet, Horseshoe, Laplace, multivariate t, g-and-k, the extreme-value pair) and deepening what can be computed generically across all of them.
◆ Where it's heading
The generic-computation thread is the one that matters and it has been building steadily: a Monte Carlo default method for cdf(), has_symmetry() to let algorithms specialise, hdr() moving to exact results for symmetric distributions and 4096 quantiles elsewhere, open-versus-closed support intervals. Version 0.8.0 is where that thread arrives somewhere — arithmetic on arbitrary distributions, with closed forms used when they exist and numerical convolution when they do not. The package is positioning itself as a computational layer rather than a catalogue, which is consistent with how weird and the forecasting packages consume it.
◆ Prediction
Expect the numerical machinery behind dist_convolved() to be reused for other operators, and more generics like has_symmetry() that let downstream algorithms take exact paths when a distribution supports them.

Frequently asked questions
What is the difference between cairo and distributional?
They serve adjacent needs but don't currently overlap on shipped themes. cairo and distributional are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Is cairo better than distributional?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. cairo and distributional are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
