STACAS
Single-cell batch correction that learned to use cell labels, then spent three releases chasing Seurat.
A side-by-side editorial comparison of nipnTK and sdsfun — release velocity, themes, recent moves, and the top alternatives to consider.
nipnTK's toolkit is settled; the last two years have gone into packaging, not methods.
An R implementation of the NiPN anthropometric data-quality checks — age heaping, age ratio tests, digit preference and the rest. The methods have been stable since the first CRAN release in 2020; the substantive change since was fixing ageRatioTest() for missing and numeric age values, shipped as a GitHub development release in April 2024 and to CRAN the next day. The most recent release is explicitly routine upkeep: refactored functions, a test for age heaping, pkgdown moved to the nutriverse template, citation and funding metadata.
A spatial-statistics utility package exists to be depended on, and is built accordingly.
sdsfun collects spatial data science utilities — neighbour lists, spatial constrained clustering, discretization, dummy variable generation, geographical detector statistics and projection helpers — with the computationally heavy parts implemented in Rcpp. It was assembled quickly across late 2024, adding a function set roughly every three weeks, and has slowed since to a couple of releases a year. The most recent work is corrective: no longer initializing the RNG state at load, fixing matrix inputs misread as vectors, and clearing an Armadillo deprecation.

This is a maintained reference implementation rather than an evolving product. Release notes are dominated by repository plumbing — CI workflows, website templates, badges, CITATION files — which is what a package looks like once its statistical surface is complete and the work shifts to keeping it installable and citable. The nutriverse pkgdown template and shared conventions place it inside a family of nutrition packages from the same maintainer rather than standing alone.
Expect continued maintenance releases driven by CRAN policy and the nutriverse template rather than new checks, since two of the last three releases contained no method changes at all.

The most recent work is corrective: no longer initializing the RNG state at load, fixing matrix inputs misread as vectors, and clearing an Armadillo deprecation.
This is infrastructure for a family of packages rather than an end-user tool, and the changelog says so directly — functions were added to support gdverse and sesp, and moran_test was migrated in from geocomplexity. That migration pattern is the defining move: capability consolidates here so the downstream packages can share it instead of each carrying its own copy. Growth has slowed as that consolidation completed, leaving correctness and dependency upkeep.
Given the package moves when its dependents need something, the next release most likely brings in another shared function or responds to a downstream requirement rather than following its own plan. Armadillo and CRAN check changes remain the reliable source of maintenance work.
