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 pak?

pak's roadmap is written by enterprise R deployments and Posit Package Manager.

pak is the fast, parallel package installer for R. Recent releases concentrate almost entirely on environments where R runs behind a corporate boundary: Posit Package Manager single sign-on, private PPM instances serving source where a binary was requested, custom HTTPS certificates, and genuinely offline Bioconductor behaviour.

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.

5.0

pak's roadmap is written by enterprise R deployments and Posit Package Manager.

◆ Current state

pak is the fast, parallel package installer for R. Recent releases concentrate almost entirely on environments where R runs behind a corporate boundary: Posit Package Manager single sign-on, private PPM instances serving source where a binary was requested, custom HTTPS certificates, and genuinely offline Bioconductor behaviour.

◆ Where it's heading

Two currents run together. One is enterprise plumbing — authentication, certificates, private repositories. The other is meeting repositories where they actually are, auto-detecting an R package in a subdirectory of a multi-language GitHub repo and restoring installs from releases and pull requests.

◆ Prediction

Expect continued PPM-driven work and more remote-resolution edge cases as monorepos and non-standard repository layouts become the norm.
