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 LightLogR?

Wearable light-exposure data gets circular time and versioned device formats

LightLogR ingests recordings from wearable light loggers and optical radiation dosimeters, and its release notes are lopsided: four of the six most recent tags are one-line merge stubs while 0.10.0 carries several thousand words. That release is where the package sits — dataset-wide summary tables, a version argument on the importers, and time of day handled as a circular quantity.

JointFPM vs LightLogR: editorial side-by-side

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.

Wearable light-exposure data gets circular time and versioned device formats

◆ Current state

LightLogR ingests recordings from wearable light loggers and optical radiation dosimeters, and its release notes are lopsided: four of the six most recent tags are one-line merge stubs while 0.10.0 carries several thousand words. That release is where the package sits — dataset-wide summary tables, a version argument on the importers, and time of day handled as a circular quantity.

◆ Where it's heading

The arc runs from reading files off N devices toward modelling the awkward shapes of chronobiology data. Circular conversion lets bedtimes crossing midnight average correctly; remove_partial_data() can demand a minimum duration rather than a fraction of a known total; add_states() takes Interval objects so sleep-scoring output flows straight in. The device side hardens in parallel — supported_versions() exists because a VEET firmware release changed the file format mid-life.

◆ Prediction

The version switch currently covers VEET and a German-locale Actiwatch Spectrum; more device-format generations behind that same argument are the obvious continuation as manufacturers revise exports. The named milestones (Civil Dawn, then Sunrise) suggest the next substantive release will be another themed one rather than a steady drip.
