What is cubist?

The R port of Quinlan's Cubist gets reproducibility fixes, not new modelling

Cubist is the R interface to Quinlan's rule-based regression model, wrapping the original C sources behind an R API and feeding the tidymodels rules package. The 0.6.0 release adds a strip_time_stamps control that removes date, time and duration information from model output, and now errors rather than silently misbehaving when a date or date-time column is passed. Error reporting moves from base stop() and warning() to cli.

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 R port of Quinlan's Cubist gets reproducibility fixes, not new modelling

◆ Current state

Cubist is the R interface to Quinlan's rule-based regression model, wrapping the original C sources behind an R API and feeding the tidymodels rules package. The 0.6.0 release adds a strip_time_stamps control that removes date, time and duration information from model output, and now errors rather than silently misbehaving when a date or date-time column is passed. Error reporting moves from base stop() and warning() to cli.

◆ Where it's heading

The direction is custodial: this is a mature algorithm with a stable definition, so the work is making a decades-old C codebase behave predictably inside a modern R workflow. The reproducibility thread is the clearest one — embedded timestamps mean two identical models compare as different objects, which breaks caching, testing and any workflow that hashes results. Alongside it runs slow C hygiene, from keyword symbol overwrites in 0.5.0 to unused-variable warnings in 0.6.0.

◆ Prediction

Expect continued small maintenance releases tracking CRAN compiler requirements and the needs of the rules package, with no change to the modelling algorithm itself.

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.
