What is PowerTOST?

A bioequivalence sample-size workhorse whose news is which regulator it now covers

PowerTOST computes power and sample size for bioequivalence and its changelog reads as a record of regulatory divergence more than statistical development. Version 1.5-3 added the Gulf Co-operation Council as a regulator setting; 1.5-4 and 1.5-6 stripped 'FDA' out of the narrow-therapeutic-index function names once China's CDE began requiring the same evaluation. The most recent release, 1.5-7, is a single fix to how nvec() splits a total sample size across sequences.

What is trackeR?

Fitness-tracking analysis in slow maintenance, still absorbing upstream breakage.

trackeR reads GPS and fitness-tracker files in TCX, GPX and JSON form and turns them into session data, distribution and concentration profiles, and route plots. Feature work concentrated in the 1.5 series in 2019; the two releases since are corrective. The latest swaps the plot layout dependencies for patchwork and fixes plot_route() returning nothing.

A bioequivalence sample-size workhorse whose news is which regulator it now covers

◆ Current state

PowerTOST computes power and sample size for bioequivalence and its changelog reads as a record of regulatory divergence more than statistical development. Version 1.5-3 added the Gulf Co-operation Council as a regulator setting; 1.5-4 and 1.5-6 stripped 'FDA' out of the narrow-therapeutic-index function names once China's CDE began requiring the same evaluation. The most recent release, 1.5-7, is a single fix to how nvec() splits a total sample size across sequences.

◆ Where it's heading

The package is in long maintenance with a widening regulatory surface: the statistical methods are settled, and releases arrive when an agency publishes a framework that can be expressed as a settings variant of an existing method. Function naming has been deliberately decoupled from any single agency, with the deprecated FDA-suffixed aliases carried for years before removal. Cadence has slowed to roughly one release every eighteen months.

◆ Prediction

The next release is most likely another regulator setting or a small fix; on the deprecation notice already given, the power.NTIDFDA()-style aliases are the obvious removal candidate.

Fitness-tracking analysis in slow maintenance, still absorbing upstream breakage.

◆ Current state

trackeR reads GPS and fitness-tracker files in TCX, GPX and JSON form and turns them into session data, distribution and concentration profiles, and route plots. Feature work concentrated in the 1.5 series in 2019; the two releases since are corrective. The latest swaps the plot layout dependencies for patchwork and fixes plot_route() returning nothing.

◆ Where it's heading

Recent releases track other people's changes: ggmap moving to Stadia maps, gridExtra giving way to patchwork, a cadence field being read into the wrong column. The 2019 entries are where the analysis surface was built out, with cumulative elevation gain, compressed file reading and elevation-noise thresholds, and it has not moved much since.

◆ Prediction

Expect the next release to be another compatibility or parsing fix rather than a new metric.

Frequently asked questions

What is the difference between PowerTOST and trackeR?

Both compete on the same themes — maintenance — within Infra & APIs. PowerTOST and trackeR 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 PowerTOST better than trackeR?

Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. PowerTOST and trackeR are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
