LightLogR vs smam: at a glance
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.
What is smam?
Animal-movement models in R, where new stochastic processes arrive years apart.
smam fits statistical models of animal movement, covering moving-resting processes with and without measurement error, moving-resting-handling, and moving-moving processes, with simulation, point estimation and variance estimation for each. The last three releases are pure upkeep: guarding Rf_error calls after an Rcpp update, a maintainer email change, and a compiler warning fix. The substantive work in this window is 0.7.0, which added estimate and vcov generics across all fit functions, and 0.6.0, which added the moving-moving process.

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.

0.0INFRA · APIS
Animal-movement models in R, where new stochastic processes arrive years apart.
◆ Current state
smam fits statistical models of animal movement, covering moving-resting processes with and without measurement error, moving-resting-handling, and moving-moving processes, with simulation, point estimation and variance estimation for each. The last three releases are pure upkeep: guarding Rf_error calls after an Rcpp update, a maintainer email change, and a compiler warning fix. The substantive work in this window is 0.7.0, which added estimate and vcov generics across all fit functions, and 0.6.0, which added the moving-moving process.
◆ Where it's heading
This package grows by adding process models, and it does so rarely. Between the moving-moving process in 2021 and now, the only interface-level change has been the 0.7.0 generics that gave every fit function a common way to retrieve estimates and their covariance, which is consolidation of an accumulated collection rather than expansion of it. The three releases since are entirely reactive to toolchain and CRAN pressure, and they arrive in step with the maintainer's other package coga, which received the same Rcpp guard within twenty minutes on the same day.
◆ Prediction
Expect further releases to be CRAN and Rcpp maintenance unless a new movement process is published, which is what has historically prompted a minor version here. The generics added in 0.7.0 give any future process model a ready-made interface to slot into.

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