What is bayestools?

The JAGS toolkit under RoBMA, shipping the standardization machinery its downstream rewrite needed

BayesTools provides the shared JAGS fitting, prior and summary infrastructure that the author's meta-analysis packages build on. The 0.2.x line filled in modeling primitives — prior_mixture() and mixed-posterior objects in 0.2.18, expression-valued priors and lme4-style uncorrelated random effects in 0.2.20, then a run of small diagnostic fixes for mixture and spike-and-slab priors. Version 0.3.0 in May 2026 adds automatic standardization of continuous predictors, default priors for unspecified factor and continuous terms, and functions to transform prior and posterior samples back to the original scale.

What is yahoofinancer?

A Yahoo Finance client that spent four years chasing API drift before adding bulk retrieval

yahoofinancer wraps the Yahoo Finance API for R. Its first four releases are almost entirely repair work: 0.2.0 existed only to absorb upstream API changes, 0.3.0 and 0.4.0 fixed row mismatches, a wrong quote endpoint, a broken options call, and valuation columns returning identical values. Version 0.5.0 in June 2026 is the first release to add capability rather than restore it, introducing a Tickers class that fetches pricing, valuation and history for a vector of symbols in one call.

The JAGS toolkit under RoBMA, shipping the standardization machinery its downstream rewrite needed

◆ Current state

BayesTools provides the shared JAGS fitting, prior and summary infrastructure that the author's meta-analysis packages build on. The 0.2.x line filled in modeling primitives — prior_mixture() and mixed-posterior objects in 0.2.18, expression-valued priors and lme4-style uncorrelated random effects in 0.2.20, then a run of small diagnostic fixes for mixture and spike-and-slab priors. Version 0.3.0 in May 2026 adds automatic standardization of continuous predictors, default priors for unspecified factor and continuous terms, and functions to transform prior and posterior samples back to the original scale.

◆ Where it's heading

This package's releases are best read against what depends on them. The 0.2.x fixes track features appearing in RoBMA one version later, and 0.3.0 landed a single day before RoBMA 4.0.0 — the standardization and sample-transformation functions are the substrate that rewrite needed. The direction of the work is toward sensible defaults: default priors by predictor type, automatic standardization for sampling stability, and transformation back to interpretable scale so the convenience does not cost the user their units.

◆ Prediction

Given how tightly its releases track downstream needs, the next version is most likely driven by gaps surfacing in RoBMA 4.0.x rather than by independent feature work.

A Yahoo Finance client that spent four years chasing API drift before adding bulk retrieval

◆ Current state

yahoofinancer wraps the Yahoo Finance API for R. Its first four releases are almost entirely repair work: 0.2.0 existed only to absorb upstream API changes, 0.3.0 and 0.4.0 fixed row mismatches, a wrong quote endpoint, a broken options call, and valuation columns returning identical values. Version 0.5.0 in June 2026 is the first release to add capability rather than restore it, introducing a Tickers class that fetches pricing, valuation and history for a vector of symbols in one call.

◆ Where it's heading

The package is moving from single-asset lookups to portfolio-scale retrieval, and doing so without disturbing the existing path — the original Ticker class stays for single-asset deep dives while Tickers handles bulk. That parallel-class approach avoids a breaking change, but it means the package now carries two object models for the same data. The dependence on an undocumented upstream API remains the structural risk: two of the five releases here exist purely because Yahoo changed something.

◆ Prediction

Further breakage-driven patches are the safest expectation given the history, with any new work likely extending the Tickers class to the remaining single-ticker endpoints.
