calculus vs rvMF
A side-by-side editorial comparison of calculus and rvMF — release velocity, themes, recent moves, and the top alternatives to consider.
calculus vs rvMF: 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 rvMF?
A fast von Mises-Fisher sampler that ships a citation more often than a feature.
rvMF generates pseudo-random vectors from the von Mises-Fisher distribution, the standard model for directional data on a sphere. Its released surface has not changed materially in the window: the three most recent tags cover a dropped dependency, a citation update, and a C++ linking correction. The February 2026 release removes the scModels import.

◆ 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.
rvMF
0.0INFRA · APIS
A fast von Mises-Fisher sampler that ships a citation more often than a feature.
◆ Current state
rvMF generates pseudo-random vectors from the von Mises-Fisher distribution, the standard model for directional data on a sphere. Its released surface has not changed materially in the window: the three most recent tags cover a dropped dependency, a citation update, and a C++ linking correction. The February 2026 release removes the scModels import.
◆ Where it's heading
This is a single-purpose sampler that reached its intended scope early and has been maintained rather than extended since. The visible work is dependency reduction and paper-and-citation housekeeping, which is the normal shape for a method package whose implementation is described in a published paper and whose correctness argument lives there rather than in the changelog.
◆ Prediction
More of the same: occasional releases to keep the C++ layer building and the dependency list short. Nothing in the notes points toward new distributions or new sampling methods.

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