Pattern fills for ggplot2, hardened against the ways users write sizes
A side-by-side editorial comparison of detectseparation and dubicube — 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.
dubicube grew from a bootstrap helper into the uncertainty layer other B-Cubed packages call.
dubicube supplies bootstrapping and confidence-interval machinery for biodiversity data cubes in the B-Cubed project. The 0.10–0.12 series added the things a library needs to be depended on rather than copied: automatic detection of group-specific versus whole-cube bootstrapping, an optional boot backend, and then a second capability area in 0.12.0 with data quality diagnostics and cube filtering. The sibling indicator package b3gbi now delegates its confidence intervals here.

Version 0.4 in April 2026 adds the ability to distinguish complete from quasi-complete separation via separation_type.
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.

Release notes are terse — usually one line and an issue number — but the direction is legible in what gets automated. Decisions the caller used to make explicitly are being inferred: resampling scope in 0.10.0, the no-bias option in 0.11.0, and process_cube_args threaded through filter_cube() so the filtering path matches cube processing. The diagnostics work in 0.12.x is the newer line, and 0.12.2's rename of the heatmap option to rule suggests that surface is still settling.
The diagnostics and filtering additions have needed a follow-up fix in each of the two releases since they landed, so the next release is most likely more consolidation there rather than a new capability area.
