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 eratosthenes?

eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.

eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().

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.

eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.

◆ Current state

eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().

◆ Where it's heading

The package is moving from research code to something a non-author can run. Consolidating estimation behind one function, then wrapping every input class in a validator, are the two steps that make failures legible instead of cryptic, and the diagnostics added earlier serve the same end for the sampler itself. Nothing in the window changes the underlying model; the work is all about making it usable and its output checkable.

◆ Prediction

With inputs validated and diagnostics in place, the next release is more likely to extend the constraint or assemblage modelling than to keep reworking the interface, though the feed's three sparse tags give little to read a cadence from.
