STACAS
Single-cell batch correction that learned to use cell labels, then spent three releases chasing Seurat.
A side-by-side editorial comparison of roclang and sdsfun — release velocity, themes, recent moves, and the top alternatives to consider.
A roxygen2 documentation-reuse helper whose release notes are mostly upstream damage control.
roclang lets package authors pull documentation text out of an existing function's roxygen block and splice it into their own — extract_roc_text() with type = "param", "dot_params" or a section selector. The feature surface has been stable since 0.2.1; the parameter-matching rules and the checks for invalid or ambiguous extractions are the substance of what shipped.
A spatial-statistics utility package exists to be depended on, and is built accordingly.
sdsfun collects spatial data science utilities — neighbour lists, spatial constrained clustering, discretization, dummy variable generation, geographical detector statistics and projection helpers — with the computationally heavy parts implemented in Rcpp. It was assembled quickly across late 2024, adding a function set roughly every three weeks, and has slowed since to a couple of releases a year. The most recent work is corrective: no longer initializing the RNG state at load, fixing matrix inputs misread as vectors, and clearing an Armadillo deprecation.

Nearly every release since 0.2.0 has been reactive. The package parses documentation text produced by other packages, so a wording change in stats::lm()'s documentation breaks its test suite, and a roxygen2 selection-semantics change forces its parameter matching to follow. The 0.2.3 release is exactly this pattern again. Release cadence has slowed to roughly one entry every two years, and the last two carried no functional change at all.
Further releases are most likely triggered by upstream roxygen2 or base R documentation edits breaking tests rather than by new extraction capability. The entries show no queued feature work.

This is infrastructure for a family of packages rather than an end-user tool, and the changelog says so directly — functions were added to support gdverse and sesp, and moran_test was migrated in from geocomplexity. That migration pattern is the defining move: capability consolidates here so the downstream packages can share it instead of each carrying its own copy. Growth has slowed as that consolidation completed, leaving correctness and dependency upkeep.
Given the package moves when its dependents need something, the next release most likely brings in another shared function or responds to a downstream requirement rather than following its own plan. Armadillo and CRAN check changes remain the reliable source of maintenance work.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
Both compete on the same themes — r-package — within Analytics. roclang and sdsfun 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. roclang and sdsfun are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
