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 gwasvcf?

gwasvcf has stopped adding features and now just keeps proxy matching from failing.

gwasvcf reads and queries GWAS summary statistics stored as VCF, with LD proxy lookup as its most-used entry point. Every release in the visible window is a fix, and all but one land in or around proxy_match(). The last functional addition was gwasvcf_to_summaryset() in 0.1.2, which hands data to gwasglue2 rather than doing new work here.

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.

gwasvcf has stopped adding features and now just keeps proxy matching from failing.

◆ Current state

gwasvcf reads and queries GWAS summary statistics stored as VCF, with LD proxy lookup as its most-used entry point. Every release in the visible window is a fix, and all but one land in or around proxy_match(). The last functional addition was gwasvcf_to_summaryset() in 0.1.2, which hands data to gwasglue2 rather than doing new work here.

◆ Where it's heading

The package is in custodial maintenance inside the MRC IEU OpenGWAS stack, and its releases are reactive: each one answers a specific user-reported failure, credited to the reporter. The 0.1.6 pattern is telling — rather than replace the proxy VCF construction, it keeps the original path and adds a fallback only for inputs that fail, so existing results are left bit-for-bit unchanged.

◆ Prediction

Expect further narrow robustness fixes to proxy_match() driven by user-reported VCF shapes; nothing in the entries suggests new analysis capability is being built here rather than in gwasglue2.

Frequently asked questions

What is the difference between constants and gwasvcf?

They serve adjacent needs but don't currently overlap on shipped themes. constants and gwasvcf 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 gwasvcf?

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