CHNOSZ vs pivottabler
A side-by-side editorial comparison of CHNOSZ and pivottabler — release velocity, themes, recent moves, and the top alternatives to consider.

CHNOSZ vs pivottabler: at a glance
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 pivottabler?
The pivot table package that ships only when R itself changes underneath it.
pivottabler builds pivot tables in R and renders them to HTML, LaTeX and Excel, with Word, PowerPoint and PDF reachable through its sibling basictabler and flextable. The feature work finished years ago — the last substantial additions were the outline layout and the enhancement batches of 2020. Since then the release stream tracks R's own release notes rather than any roadmap of its own.
CHNOSZ vs pivottabler: editorial side-by-side
CHNOSZ
0.0INFRA · APIS
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.
pivottabler
0.0INFRA · APIS
The pivot table package that ships only when R itself changes underneath it.
◆ Current state
pivottabler builds pivot tables in R and renders them to HTML, LaTeX and Excel, with Word, PowerPoint and PDF reachable through its sibling basictabler and flextable. The feature work finished years ago — the last substantial additions were the outline layout and the enhancement batches of 2020. Since then the release stream tracks R's own release notes rather than any roadmap of its own.
◆ Where it's heading
Three of the last four releases exist because base R changed: is.atomic(NULL) in 4.4.0, match() and %in% on date types in 4.3.0, stringsAsFactors in 4.1.0. The one genuine feature in that stretch, lowN and highN in findCells(), is a convenience on top of machinery that already existed. The package and basictabler move as a pair — the 2021 Excel fix was shipped from both sides two minutes apart, and both got their CRAN-notes release on the same afternoon in April 2025.
◆ Prediction
Expect the next release to be triggered by another base R change or a CRAN check, not by a feature; the pairing with basictabler means it will likely arrive within minutes of its sibling's.
