A tables-listings-graphs package that reached CRAN and then went quiet.
A side-by-side editorial comparison of ijtiff and spatsoc — release velocity, themes, recent moves, and the top alternatives to consider.
A TIFF reader for scientific imaging that spent its recent releases shedding weight and fixing memory bugs.
ijtiff reads and writes TIFF files the way ImageJ writes them, which ordinary R TIFF readers get wrong — multi-channel, multi-frame, and unusual bit depths. The 3.1.x line is dominated by memory correctness in the C tag-handling layer, alongside dropping the large imager dependency from the display path. Cadence is sporadic, with multi-year gaps.
One maintainer, one or two new collective-motion metrics per release, for two years straight
spatsoc turns animal relocation data into spatial and social groupings — dyads, fission-fusion events, group centroids — and the recent history is a metronomic accretion of collective-motion measures on top of that base. Since late 2024 nearly every release has added one or two: polarization, direction to leader, position along the group axis, directional correlation delay, edge alignment, edge zones. Development is essentially single-handed; almost every merged PR in this window carries the same author.

Two threads run through the window. The C layer is being hardened — memory leaks in tag handling, buffer cleanup, PROTECT errors, validation of malformed files — which is the kind of work that surfaces when a package gets run against real-world files at volume. Separately, the R layer is shedding dependencies, with base graphics replacing imager for display. Both make the package cheaper and safer to depend on rather than more capable.
Expect continued C-level correctness work rather than format features, since three of the last three substantive releases were memory or compiler fixes.

The December 2025 release changes register. Alongside three new calc_distance / calc_direction / calc_centroid functions and an internal assertion family, it deprecates the `projection` argument in favour of `crs` and lands a round of checks and tests explicitly staged ahead of a new spatial interface. Read together, that is a package finishing its metric catalogue and starting to rework the coordinate-handling layer underneath it to match modern R-spatial conventions — the same evolution that made it drop its startup warning back in 0.2.7.
The next release is likely the spatial-interface rework the 0.2.12 test and assertion work was staged for, with `projection` moving from deprecated to removed. Feature additions should slow while that lands.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
They serve adjacent needs but don't currently overlap on shipped themes. ijtiff and spatsoc 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. ijtiff and spatsoc are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
