Nexus does the diagnosis; the agent is now reaching into the status page too.
A side-by-side editorial comparison of calculus and sociome — release velocity, themes, recent moves, and the top alternatives to consider.
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.
A six-year silence ends with the Area Deprivation Index rebuilt on the 2020 census.
sociome computes the Area Deprivation Index and related measures of social determinants of health from US census data. After patch releases in 2019 and 2020 the package went quiet, and version 3.0.0 in January 2026 returns with complete 2020 decennial census support, expanded ZCTA coverage, and helper objects that tell users up front which dataset, year and geography combinations the census API will actually serve.

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.
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.

The package's usefulness is tied to a data generation, and this release moves it a full census cycle forward. The other changes point the same way: better input checking so failures surface before an API call rather than after, a documented availability matrix, and removal of the seed argument from the three main entry points. That last one is a breaking change and suggests the underlying computation stopped being stochastic in the way it was.
With 2020 support landed, the pressure shifts to annual American Community Survey vintages rather than decennial ones. Expect maintenance around that rather than another overhaul.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
They serve adjacent needs but don't currently overlap on shipped themes. calculus and sociome 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.
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. calculus and sociome are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
