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 TidyDensity — 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 distribution catalogue that grows by one family at a time, and rarely breaks anything.
TidyDensity generates tidy-format random data from statistical distributions, with parameter estimation, AIC calculation, summary tables and automatic plotting for each one. Its releases follow a fixed template — breaking changes, new features, minor fixes — and the breaking section is usually empty. Growth comes distribution by distribution: Bernoulli, Burr, triangular, chi-square, zero-truncated negative binomial and others each arrive with a matching set of param_estimate, aic and stats_tbl helpers.

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.

The package is filling out a matrix rather than changing shape — every new distribution gets the same four or five companion functions, so the surface grows predictably and the design does not. What variation exists comes from utilities that work across distributions: MCMC sampling, bootstrap helpers, time series conversion, distribution comparison. The two genuine breaking changes in this window were both internal reworks, moving generation onto data.table and rewriting quantile normalization for speed.
The established pattern of adding a distribution with its full helper set is the most likely continuation. Recent releases have been small, suggesting the catalogue is approaching the distributions its author considers worth covering.

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