eratosthenes vs tidynorm: at a glance
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().
What is tidynorm?
Vowel normalization for phonetics, three releases deep and all of them maintenance.
tidynorm applies speaker normalization to acoustic phonetic measurements inside tidyverse pipelines, including DCT-smoothed formant trajectories through reframe_with_dct_smooth(). The visible release history is short and quiet: settable verbosity options, two fixes to the DCT smoother, and two patches chasing dependency changes in RcppArmadillo and checkmate.

◆ 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.
tidynorm
0.0INFRA · APIS
Vowel normalization for phonetics, three releases deep and all of them maintenance.
◆ Current state
tidynorm applies speaker normalization to acoustic phonetic measurements inside tidyverse pipelines, including DCT-smoothed formant trajectories through reframe_with_dct_smooth(). The visible release history is short and quiet: settable verbosity options, two fixes to the DCT smoother, and two patches chasing dependency changes in RcppArmadillo and checkmate.
◆ Where it's heading
What the entries show is a package past its build-out and into upkeep. The only user-facing addition in the window is control over how loudly the functions report themselves, which is the kind of request that arrives once people are running the package over large datasets rather than a handful of speakers. The two DCT smoother fixes are more telling about substance: returning smooths matching each original token's length, and not erroring on rate and acceleration derivatives, both matter for anyone working with formant trajectories rather than single-point measurements.
◆ Prediction
Nothing in these notes signals feature work in progress, so the next release is most likely another dependency-tracking patch unless the smoothing functions attract more use.
