discretetests vs skytrackr: at a glance
What is discretetests?
Four years of releases land in four minutes as the changelog gets backfilled to GitHub
DiscreteTests computes exact p-values and their full support for discrete statistical tests, returning results as a class that carries the observations, the test statistic and the null distribution. All four visible releases were tagged within four minutes of each other on a single day in May 2026, in reverse order — 0.4.1 carries the earliest timestamp and 0.4.0 the latest — so this is a historical changelog being pushed to GitHub at once, not four days of work.
What is skytrackr?
Light-based animal geolocation gets a second model that stops assuming the bird sat still.
skytrackr estimates animal positions from logger light data by fitting a sky-illuminance model. Three releases span the history: a 2023 v0.9 the author called functional but unpolished, a CRAN-compliant v1.0 in October 2025 that added batch reading and twilight screening, and a v2.0 six weeks later that is the first structural expansion. v2.0 pulls the data-selection and calibration steps out of the main skytrackr() call and exposes them as stk_filter(), stk_calibrate() and stk_center().

◆ Current state
DiscreteTests computes exact p-values and their full support for discrete statistical tests, returning results as a class that carries the observations, the test statistic and the null distribution. All four visible releases were tagged within four minutes of each other on a single day in May 2026, in reverse order — 0.4.1 carries the earliest timestamp and 0.4.0 the latest — so this is a historical changelog being pushed to GitHub at once, not four days of work.
◆ Where it's heading
Read by version rather than by timestamp, the package grew from binomial, Fisher, McNemar and Poisson tests into rank-based and resampling territory: Wilcoxon signed rank and rank sum, Mann-Whitney U, a conditional homogeneity test, then sign tests and a general permutation test with several built-in statistics. Alongside that the result class was extended to hold ragged observation lists and computational detail, the print output was rewritten on cli, and the old dot-separated function names were made defunct.
◆ Prediction
The permutation test with pluggable statistics is the most open-ended addition here, and adding further built-in statistics to it is the cheapest way to extend the package from where it now stands.

Light-based animal geolocation gets a second model that stops assuming the bird sat still.
◆ Current state
skytrackr estimates animal positions from logger light data by fitting a sky-illuminance model. Three releases span the history: a 2023 v0.9 the author called functional but unpolished, a CRAN-compliant v1.0 in October 2025 that added batch reading and twilight screening, and a v2.0 six weeks later that is the first structural expansion. v2.0 pulls the data-selection and calibration steps out of the main skytrackr() call and exposes them as stk_filter(), stk_calibrate() and stk_center().
◆ Where it's heading
The arc is toward exposing internals the package used to hide. Each release takes a step that was buried inside the main fitting call and turns it into a function the researcher can inspect, plot and constrain, with the scale parameter now estimated across a whole dataset rather than guessed. The new individual light model is the sharper turn: it drops the stationarity assumption behind the original diurnal fit and solves each observation along a constant-bearing course from the previous position.
◆ Prediction
The author describes the individual model's robustness as still being evaluated and its convergence as more fickle than the diurnal approach, so the next release most likely tunes convergence and documents when each model applies rather than adding a third.

Frequently asked questions
What is the difference between discretetests and skytrackr?
Both compete on the same themes — r-package — within Infra & APIs. discretetests and skytrackr 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 discretetests better than skytrackr?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. discretetests and skytrackr are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
