onemap vs squat
A side-by-side editorial comparison of onemap and squat — release velocity, themes, recent moves, and the top alternatives to consider.
onemap vs squat: at a glance
What is onemap?
A genetic-mapping mainstay that now points new users toward MAPpoly at load time
OneMap constructs genetic linkage maps for experimental crosses, and its 3.x line turned it into a hub in a wider mapping toolchain: export functions for VIEWpoly and QTLpoly, summary and interactive ordering functions adapted from MAPpoly, and retention of reference and alternative allele information from imported VCFs. The most recent release, 3.2.0 in January 2025, adds an announcement about MAPpoly to the README and the package load message, fixes a subscript-out-of-bounds warning in rf_2pts and refreshes vignettes and tests.
What is squat?
Quaternion time series got their own statistics package, and it is still filling in the toolbox.
squat treats a sequence of rotations as a statistical object: quaternion time series with means, medians, distances, principal components and clustering defined on them rather than on the raw coordinates. Version 0.5.0 adds derived representations, turning a QTS into a smooth b-spline curve or into angular velocity and acceleration. The release cadence is roughly annual.

◆ Current state
OneMap constructs genetic linkage maps for experimental crosses, and its 3.x line turned it into a hub in a wider mapping toolchain: export functions for VIEWpoly and QTLpoly, summary and interactive ordering functions adapted from MAPpoly, and retention of reference and alternative allele information from imported VCFs. The most recent release, 3.2.0 in January 2025, adds an announcement about MAPpoly to the README and the package load message, fixes a subscript-out-of-bounds warning in rf_2pts and refreshes vignettes and tests.
◆ Where it's heading
Versions 3.0.0 and 3.1.0 were driven by a benchmarking preprint on genotyping-by-sequencing best practice, and their content follows directly: marker filtering from two-point estimates, memory reduction after filtering, and optimisation of find_bins and map_avoid_unlinked. What has happened since is signposting rather than capability — a package that spent two releases integrating with MAPpoly now tells users about it every time it loads. The pre-3.0 tags are backfilled, with versions 2.3 through 2.7 sharing a single August 2021 timestamp, so their order carries no information.
◆ Prediction
The load-message announcement suggests attention is flowing toward the MAPpoly side of the toolchain; expect maintenance and compatibility releases here rather than new mapping algorithms.

0.0INFRA · APIS
Quaternion time series got their own statistics package, and it is still filling in the toolbox.
◆ Current state
squat treats a sequence of rotations as a statistical object: quaternion time series with means, medians, distances, principal components and clustering defined on them rather than on the raw coordinates. Version 0.5.0 adds derived representations, turning a QTS into a smooth b-spline curve or into angular velocity and acceleration. The release cadence is roughly annual.
◆ Where it's heading
Each release has added either a representation or a way to compare series. First the class and the core statistical methods, then clustering algorithms and distance matrices, then quaternion algebra and axis-angle conversion, then rotation-invariant elastic distance and roll-pitch-yaw. The package is broadening the input side, so that data arriving in any of the usual rotation encodings can enter the same analysis. Dependency reduction runs alongside, with purrr and furrr swapped out for base and future.apply.
◆ Prediction
Given the pattern, the next additions are most likely further transformations and distances rather than new inference machinery. The tight coupling to fdacluster, which the notes repeatedly adapt to, means that package's API is the main external constraint on timing.

Frequently asked questions
What is the difference between onemap and squat?
They serve adjacent needs but don't currently overlap on shipped themes. onemap and squat 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 onemap better than squat?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. onemap and squat are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
