What is constants?

The R package for CODATA constants rebuilt its symbol table on NIST's naming so future updates stop being hand work.

constants exposes the CODATA recommended values of the physical constants to R, as a data frame plus symbol lists that carry units, uncertainties, or both. The package reached 1.0.0 on the 2018 CODATA release and has shipped once since, purely to track a units package update. Its surface is small and its release cadence is bound to CODATA, which revises every few years.

What is TAF?

TAF keeps turning ICES stock assessments into reproducible, dependency-pinned projects.

TAF is the R tooling behind the ICES Transparent Assessment Framework, which standardizes how fish stock assessments are laid out, sourced and rerun. The 4.3.0 release is the largest in years, adding roughly ten functions covering dependency installation and analysis, software version checks, directory inspection and README drafting. The package has carried zero non-base dependencies since 4.0.0, and the new work is careful not to break that.

The R package for CODATA constants rebuilt its symbol table on NIST's naming so future updates stop being hand work.

◆ Current state

constants exposes the CODATA recommended values of the physical constants to R, as a data frame plus symbol lists that carry units, uncertainties, or both. The package reached 1.0.0 on the 2018 CODATA release and has shipped once since, purely to track a units package update. Its surface is small and its release cadence is bound to CODATA, which revises every few years.

◆ Where it's heading

The direction set at 1.0.0 was to stop being a curated convenience wrapper and become a mechanical mirror of NIST. Hand-crafted symbol names were replaced with NIST's own ASCII symbols, categories adopted NIST's, and uncertainty switched from relative to absolute — all framed by the maintainer as necessary to make future CODATA updates routine. On top of that the package gained a correlation matrix and optional integration with the quantities package, moving it from a lookup table toward something that can propagate uncertainty.

◆ Prediction

Having rebuilt the symbol table specifically so CODATA revisions become mechanical, the next substantive release most likely tracks a new CODATA dataset rather than adding API. The experimental correlated-value support, disabled by default at 1.0.0, is the one part these entries flag as unfinished.

TAF keeps turning ICES stock assessments into reproducible, dependency-pinned projects.

◆ Current state

TAF is the R tooling behind the ICES Transparent Assessment Framework, which standardizes how fish stock assessments are laid out, sourced and rerun. The 4.3.0 release is the largest in years, adding roughly ten functions covering dependency installation and analysis, software version checks, directory inspection and README drafting. The package has carried zero non-base dependencies since 4.0.0, and the new work is careful not to break that.

◆ Where it's heading

The arc runs from analysis runner to project toolkit. Early 3.x releases built out the bootstrap and metadata machinery; 4.0.0 renamed the package and stripped every external dependency; 4.2.0 cleaned up vocabulary that confused users. 4.3.0 turns outward to the people running assessments — install.deps(), pdeps() and check.software() address reproducing someone else's environment, while draft.readme(), taf.example() and dir.tree() address understanding an unfamiliar project.

◆ Prediction

Expect the follow-up work to harden the new dependency functions rather than add more surface, since 4.3.1 arrived immediately to fix wide2long() compatibility with older R and that batch of ten functions has had little field exposure.

Frequently asked questions

What is the difference between constants and TAF?

They serve adjacent needs but don't currently overlap on shipped themes. constants and TAF are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.

Is constants better than TAF?

Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. constants and TAF are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
