What is covr?

covr's coverage tooling has been stable to the point of dormancy since 2022

covr is the de facto R code-coverage package, and its visible release history stops at 3.6.0 in August 2022. That release was the last substantive one: an opt-in test-trace recorder, a permissive MIT relicense, Google Cloud Build support, and a long list of robustness fixes. Everything before it is a slow cadence of CI-integration additions and check failures.

What is nuggets?

nuggets keeps compounding on the 2.0 rewrite — more pattern families, lighter install.

nuggets searches for association rules, contrasts and other conditional patterns in the GUHA tradition, with a C++ core behind dig() and an interactive explore() app for reading results. Since the 2.0 rewrite of that core, every release has widened the same three surfaces: more pattern families to mine, more of explore() to inspect them in, and steady performance work underneath. The most recent tag optimises dig() on sparse crisp data with a sparse bit chain and adds clustering characteristics to explore() for association rules.

covr's coverage tooling has been stable to the point of dormancy since 2022

◆ Current state

covr is the de facto R code-coverage package, and its visible release history stops at 3.6.0 in August 2022. That release was the last substantive one: an opt-in test-trace recorder, a permissive MIT relicense, Google Cloud Build support, and a long list of robustness fixes. Everything before it is a slow cadence of CI-integration additions and check failures.

◆ Where it's heading

The arc is a tool that reached feature-completeness for its niche and then stopped moving. The direction of travel while it was active was integration breadth — Codecov, Coveralls, GitHub Actions, SonarQube, Google Cloud Build — rather than deeper analysis. With no releases since 2022, the practical trajectory is that covr is maintained by its ecosystem position, not by shipping.

◆ Prediction

The entries do not support a confident prediction about the next release; there has been no visible activity in this feed for roughly four years, so the honest read is that covr is in caretaker mode.

nuggets keeps compounding on the 2.0 rewrite — more pattern families, lighter install.

◆ Current state

nuggets searches for association rules, contrasts and other conditional patterns in the GUHA tradition, with a C++ core behind dig() and an interactive explore() app for reading results. Since the 2.0 rewrite of that core, every release has widened the same three surfaces: more pattern families to mine, more of explore() to inspect them in, and steady performance work underneath. The most recent tag optimises dig() on sparse crisp data with a sparse bit chain and adds clustering characteristics to explore() for association rules.

◆ Where it's heading

Two forces are shaping the package. One is coverage: baseline, complement and paired-baseline contrasts, correlations, tautologies, ancestors and clustering have all been added as first-class dig_ or explore_ surfaces, so the same search engine now answers a widening set of questions. The other is weight — Shiny packages moved from Imports to Suggests, BH and RcppThread dropped, XSIMD updated, parse_condition() rewritten in C++ — which keeps a package with an interactive app from forcing that app's dependencies on every user. Deprecations are handled through lifecycle rather than removed abruptly.

◆ Prediction

Expect the sparse-data optimisation to extend from crisp to fuzzy data, and explore() to keep gaining tabs as each new pattern family lands, on the roughly six-week cadence the 2.2 line has held.
