Pattern fills for ggplot2, hardened against the ways users write sizes
A side-by-side editorial comparison of detectseparation and gcube — release velocity, themes, recent moves, and the top alternatives to consider.
A diagnostic package that generalized past its own name, then learned to say which kind of separation it found
detectseparation identifies separation and infinite estimates in binomial-response GLMs — the condition where maximum likelihood estimates diverge and standard software reports large coefficients with enormous standard errors instead of an error. Version 0.3 was the structural turn: detect_infinite_estimates() became the general method covering log, logit, probit and cauchit links, with detect_separation() demoted to a wrapper around it. Version 0.4 in April 2026 adds the ability to distinguish complete from quasi-complete separation via separation_type.
gcube's recent releases are all packaging metadata, not simulation code
gcube simulates biodiversity data cubes — generating occurrence points, sampling them under configurable detection bias, and designating them to a grid — as a testbed for the B-Cubed project's indicator tooling. The visible release history is almost entirely metadata and release-automation work: Zenodo grant IDs, ROR URL fixes, publisher fields, funder and rights-holder descriptions. The simulation functionality itself is not what these entries are about.

The package has been generalizing steadily — first past its own framing, since separation is one case of infinite estimates rather than the whole problem, and now toward finer classification of what it detects. The distinction 0.4 adds is practically useful because complete and quasi-complete separation call for different responses. Release intervals are long, roughly two to four years, which fits a diagnostic tool whose underlying theory is settled.
With link coverage broad and separation now classified by type, further work is more likely to refine reporting than to extend detection to new model families.

The simulation functionality itself is not what these entries are about.
The February 2026 cluster reads as a package wiring up its archival identity rather than developing: four releases in four days, one of them explicitly a test of the GitHub release path. That is characteristic of research software preparing to be cited — a Zenodo DOI, correct funder attribution and a checklist-compliant description are the deliverables when the funder requires them. Substantive work on mapping functions and grid designation appears earlier and only through tutorial fixes.
With the Zenodo integration and metadata now settled, expect attention to return to the simulation functions themselves, most likely driven by what the sibling indicator packages need to test against.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
They serve adjacent needs but don't currently overlap on shipped themes. detectseparation and gcube 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.
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. detectseparation and gcube are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
