What is dittodb?

dittodb has spent four years on CRAN link fixes and one DBI bump.

dittodb records and replays database interactions so tests can run without a live database, sitting behind DBI and dbplyr. The visible history splits cleanly in two: functional work through 0.1.8 broadening which databases and situations can be captured, then three consecutive maintenance releases. The most recent adds DBI 1.3.0 compatibility and nothing else.

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().

dittodb has spent four years on CRAN link fixes and one DBI bump.

◆ Current state

dittodb records and replays database interactions so tests can run without a live database, sitting behind DBI and dbplyr. The visible history splits cleanly in two: functional work through 0.1.8 broadening which databases and situations can be captured, then three consecutive maintenance releases. The most recent adds DBI 1.3.0 compatibility and nothing else.

◆ Where it's heading

The functional direction was always coverage: more databases, more situations that can be mocked, better failure messages when the recording setup is wrong. That work stopped after 0.1.8 in 2024, and the package has since only answered CRAN link checks and a DBI release. Full transaction support with separate mock directories was flagged as planned back in 0.1.4 and has not appeared.

◆ Prediction

The last three releases are pure upkeep, so the next most likely tracks another DBI or dbplyr change rather than delivering the transaction support still outstanding.

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.
