calculus vs hicp
A side-by-side editorial comparison of calculus and hicp — release velocity, themes, recent moves, and the top alternatives to consider.
calculus vs hicp: at a glance
What is calculus?
A published calculus engine whose last two years produced one overloaded method
calculus provides high-dimensional numerical and symbolic calculus in R — differentiation, integration, tensor operations and, since the 0.3.0 restructure, ordinary differential equations. It was published in the Journal of Statistical Software in 2022, which is the event the 1.0.0 release records rather than any code change. Since then it has produced two releases: a documentation site move, and in July 2025 an overload of is.numeric to include complex numbers.
What is hicp?
Eurostat's inflation package moved its whole taxonomy to ECOICOP 2 and broke the old one on purpose.
hicp downloads and computes the Harmonised Index of Consumer Prices, and it is maintained inside Eurostat rather than around it. Version 1.1.0 switches the package default to ECOICOP version 2 for HICP, converts the spec.aggs and countries datasets into functions that answer per COICOP version, and drops the bundle-code machinery that only the older classification needs.

◆ Current state
calculus provides high-dimensional numerical and symbolic calculus in R — differentiation, integration, tensor operations and, since the 0.3.0 restructure, ordinary differential equations. It was published in the Journal of Statistical Software in 2022, which is the event the 1.0.0 release records rather than any code change. Since then it has produced two releases: a documentation site move, and in July 2025 an overload of is.numeric to include complex numbers.
◆ Where it's heading
The release history divides cleanly at the JSS publication. Everything before it is development plus the CRAN and pre-review fixes needed to get there; everything after is incidental. The complex-number overload fits the package's positioning around symbolic and high-dimensional work, where complex values arise naturally, but it is one method and the notes say nothing more.
◆ Prediction
Expect releases only when a CRAN check or a downstream dependency forces one; nothing in these entries points to planned additions to the numerical or symbolic engines.

0.0INFRA · APIS
Eurostat's inflation package moved its whole taxonomy to ECOICOP 2 and broke the old one on purpose.
◆ Current state
hicp downloads and computes the Harmonised Index of Consumer Prices, and it is maintained inside Eurostat rather than around it. Version 1.1.0 switches the package default to ECOICOP version 2 for HICP, converts the spec.aggs and countries datasets into functions that answer per COICOP version, and drops the bundle-code machinery that only the older classification needs.
◆ Where it's heading
Two breaking releases in seven months, each clearing a different kind of debt. 1.0.0 settled the API: consistent download-function names, aggregation split into tree-following and user-defined halves, a settings object threaded through everything. 1.1.0 then spent that stability on the classification migration. Datasets keep turning into functions, which is the tell that the package expects to serve several COICOP versions at once rather than one at a time.
◆ Prediction
The ecoicop1 compatibility path is defined but no longer the default, so the next question is how long it stays. Expect further helpers in the is.* family and continued movement of static data behind version-aware functions.

Frequently asked questions
What is the difference between calculus and hicp?
They serve adjacent needs but don't currently overlap on shipped themes. calculus and hicp 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 calculus better than hicp?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. calculus and hicp are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
