Pattern fills for ggplot2, hardened against the ways users write sizes
A side-by-side editorial comparison of animovement and detectseparation — release velocity, themes, recent moves, and the top alternatives to consider.
animovement stopped being a package and became a metapackage over seven focused ones.
animovement handles animal movement data — tracking output from pose-estimation and centroid trackers, cleaned into a standard form. Its 0.7.3 release, the first GitHub tag since November 2024, bundles the 0.5 through 0.7 development series and records a structural change: the codebase was split into aniframe, aniread, aniprocess, anicheck, animetric, anivis and anispace, which animovement now bundles and re-exports. The package has done this before at smaller scale, having renamed itself from trackballr in 0.2.0 to match a widened scope.
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.

The package has done this before at smaller scale, having renamed itself from trackballr in 0.2.0 to match a widened scope.
Development has moved to the constituent packages, which release far more often than animovement itself — aniframe, aniread and aniprocess have each shipped multiple times in 2026 while animovement tagged once. That makes animovement a stable install surface rather than where the work happens, and the ani_df data class plus the frame-rate to sampling-rate terminology change are the contracts holding the suite together. Optional dependencies are handled through animovement_install_suggested() against r-universe and Bioconductor mirrors.
With the split done and the constituent packages iterating independently, animovement releases are likely to become periodic roll-ups of the suite rather than carriers of new functionality.

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.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
They serve adjacent needs but don't currently overlap on shipped themes. animovement and detectseparation 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. animovement and detectseparation are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
