What is CHNOSZ?

A geochemistry thermodynamics engine that changed its units and its database schema in one release.

CHNOSZ computes thermodynamic properties and phase diagrams for geochemical systems, backed by OBIGT, its bundled thermodynamic database. It releases roughly once a year with a short highlights note pointing at a full changelog elsewhere. Since the 2.0.0 reset, work has been curation and communication: new species in OBIGT, a FAQ vignette, a rewritten introduction, and more readable diagram labels.

What is funcharts?

One paper, one release: the functional control chart package ships methods as they get published.

funcharts implements control charts for functional data — statistical process control where each observation is a curve rather than a number. Its release cadence maps one-to-one onto its authors' publication record: 1.4.0 delivered the robust multivariate framework from Capezza et al. (2022), 1.7.0 the adaptive chart from Centofanti et al. (2025) as it was accepted at Technometrics. Each release adds Phase I and Phase II functions for one named method.

CHNOSZ

0.0

A geochemistry thermodynamics engine that changed its units and its database schema in one release.

◆ Current state

CHNOSZ computes thermodynamic properties and phase diagrams for geochemical systems, backed by OBIGT, its bundled thermodynamic database. It releases roughly once a year with a short highlights note pointing at a full changelog elsewhere. Since the 2.0.0 reset, work has been curation and communication: new species in OBIGT, a FAQ vignette, a rewritten introduction, and more readable diagram labels.

◆ Where it's heading

2.0.0 was the structural break — Joules replacing calories as the default output of subcrt(), a required E_units column, a new model column, and the removal of a legacy scaling convention for heat-capacity coefficients. Everything since has built on that settled foundation rather than disturbing it. The direction of the last two releases is toward coverage of specific mineral systems, rare earths and uranyl among them, and toward making the package approachable, which suggests a maintainer courting new users rather than reworking the engine.

◆ Prediction

The next release most likely continues OBIGT curation for particular element systems plus vignette work; the highlights format gives no signal of engine-level changes pending.

0.0

One paper, one release: the functional control chart package ships methods as they get published.

◆ Current state

funcharts implements control charts for functional data — statistical process control where each observation is a curve rather than a number. Its release cadence maps one-to-one onto its authors' publication record: 1.4.0 delivered the robust multivariate framework from Capezza et al. (2022), 1.7.0 the adaptive chart from Centofanti et al. (2025) as it was accepted at Technometrics. Each release adds Phase I and Phase II functions for one named method.

◆ Where it's heading

The early releases were about the package as software — vectorised tensor products, precomputed B-spline inner products, faster cross-validation — and about removing assumptions, most consequentially the assumption that functional data is represented in a B-spline basis. Since 1.4.0 the software work has stopped and the package has become a delivery vehicle for the research group's methods. Robustness came first, adaptivity second, both arriving with the paper rather than ahead of it.

◆ Prediction

The next release will most likely implement whatever this group publishes next, following the same Phase I / Phase II function pairing; nothing in the feed suggests infrastructure work resuming.

Frequently asked questions

What is the difference between CHNOSZ and funcharts?

Both compete on the same themes — r-package — within Infra & APIs. CHNOSZ and funcharts 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 CHNOSZ better than funcharts?

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