A genomics workhorse whose visible release feed stops dead in mid-2020.
A side-by-side editorial comparison of multimark and trackeR — release velocity, themes, recent moves, and the top alternatives to consider.
Five years of compiler and CRAN fixes on a capture-recapture package.
multimark fits capture-mark-recapture models for populations sampled with multiple non-invasive marks, including a spatial variant. Nothing in the visible history changes the models. Every recent release responds to something outside the package: a CRAN check, a compiler flag, or an upstream package that stopped exporting a function.
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.

This is preservation rather than development. The one substantive entry, in 2021, corrected an MCMC error in multimarkClosedSCR() serious enough that the author told users to revisit past analyses; everything since has been keeping the C code compiling across platforms. Release intervals now stretch to years.
Expect the pattern to hold, with a release whenever a toolchain or upstream dependency forces one and no change to the samplers.

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

The R phone-number package stopped only parsing numbers and started asking them where they are.
A Venn diagram package whose public release notes say almost nothing — including about its copyright cleanup.
A Shiny app for choosing the right ordinal test reached CRAN in a single 90-minute burst of tags.
A new R localization package that reached CRAN and immediately downgraded itself to experimental.
An R client for HERE's location APIs, shaped almost entirely by what the vendor exposes next.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
Both compete on the same themes — maintenance — within Infra & APIs. multimark 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.
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. multimark and trackeR are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
