squat vs tealeaves
A side-by-side editorial comparison of squat and tealeaves — release velocity, themes, recent moves, and the top alternatives to consider.
squat vs tealeaves: at a glance
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.
What is tealeaves?
A leaf-temperature model that finished its job in 2020 and has stayed finished
tealeaves solves for leaf temperature from an energy balance, using explicit units to keep parameters consistent and modelling lower and upper leaf surfaces separately so sensible and latent heat loss are computed for each. The package reached its current form in 2020 across versions 1.0.2 to 1.0.5, which added direct or functional sky temperature, dplyr 1.0.0 compatibility, and fixes to a parameter-crossing bug that the new sky temperature function had introduced. The only release since, v1.0.6 in July 2022, corrects a name in the citation file, stops parallel evaluation in a vignette and fixes README links.

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.

The only release since, v1.0.6 in July 2022, corrects a name in the citation file, stops parallel evaluation in a vignette and fixes README links.
◆ Where it's heading
This is finished scientific software. The arc runs from a 1.0.0 that already described the full model, through a usability decision in 1.0.1 to accept unitless values and assign units rather than demand them, to a 2020 cluster of compatibility and correctness work around publication. Nothing since has touched the model, and the 2022 release is pure paperwork. Its most instructive entry remains 1.0.5, where a new feature silently produced incorrect parameter crossing and the fix arrived with tests to pin the behaviour.
◆ Prediction
Expect nothing unless a dependency or CRAN check forces a release; on this record any such release will be documentation and packaging rather than a change to the energy balance.

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