JointFPM vs trackeR
A side-by-side editorial comparison of JointFPM and trackeR — release velocity, themes, recent moves, and the top alternatives to consider.
JointFPM vs trackeR: at a glance
What is JointFPM?
Recurrent-event modelling settles, with mean_no() promoted to stable.
JointFPM fits joint flexible parametric models for a recurrent event process alongside a competing terminal event, and predicts the mean number of events. The visible history runs from bug fixes on the earliest CRAN releases through standardization, integration options and a summary method, ending with mean_no() declared stable. Several changes arrived through outside pull requests.
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.
JointFPM vs trackeR: editorial side-by-side
JointFPM
0.0INFRA · APIS
Recurrent-event modelling settles, with mean_no() promoted to stable.
◆ Current state
JointFPM fits joint flexible parametric models for a recurrent event process alongside a competing terminal event, and predicts the mean number of events. The visible history runs from bug fixes on the earliest CRAN releases through standardization, integration options and a summary method, ending with mean_no() declared stable. Several changes arrived through outside pull requests.
◆ Where it's heading
The arc runs from a working estimator toward a usable one: input validation and error messages first, then control over the numerical integration, then a summary method and pass-through arguments to the underlying rstpm2 fit. The latest release adds no code so much as a stability commitment to a function users were already calling.
◆ Prediction
With mean_no() stable, the next work most likely targets the prediction and standardization paths rather than the model fit itself.
trackeR
0.0INFRA · APIS
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 JointFPM and trackeR?
They serve adjacent needs but don't currently overlap on shipped themes. JointFPM 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 JointFPM better than trackeR?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. JointFPM and trackeR are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
