checklist vs nabla
A side-by-side editorial comparison of checklist and nabla — release velocity, themes, recent moves, and the top alternatives to consider.
checklist vs nabla: at a glance
What is checklist?
An institutional R quality-control package that just split its citation half into its own tool.
checklist enforces coding, documentation and metadata standards for R packages and projects at INBO, the Flemish research institute for nature and forest, and runs as both a local tool and a GitHub Action. Much of its work concerns research-output metadata — Zenodo deposits, DOIs, ORCID, ROR identifiers, organisation records — rather than code style. Its most recent major release removed that entire area from the package.
What is nabla?
nabla dropped its C++ engine to chase exact derivatives at any order.
nabla does forward-mode automatic differentiation in R using dual numbers, returning derivatives exact to machine precision rather than approximated by finite differences. It shipped as dualr in January 2026, then a day later released 0.5.0 under a changed identity: derivatives generalise from a hardcoded second order to arbitrary order through recursive nesting, and the Rcpp and C++ fast paths are deleted so the package is pure R. The current release, 0.7.1, is CRAN resubmission cleanup.

◆ Current state
checklist enforces coding, documentation and metadata standards for R packages and projects at INBO, the Flemish research institute for nature and forest, and runs as both a local tool and a GitHub Action. Much of its work concerns research-output metadata — Zenodo deposits, DOIs, ORCID, ROR identifiers, organisation records — rather than code style. Its most recent major release removed that entire area from the package.
◆ Where it's heading
The direction is decomposition. An organisation class was first superseded by a more structured pair of classes, and then the whole citation and deposit surface moved out to a separate citeme package, leaving checklist focused on project and package checking. The sibling INBOmd package picked up the new dependency within a week, which is how this family propagates a change. What remains here is narrower and more clearly named than what it started with.
◆ Prediction
Expect checklist to continue tightening its remaining project-checking scope, with further citation and metadata work landing in citeme rather than here.
nabla
0.0ANALYTICS
nabla dropped its C++ engine to chase exact derivatives at any order.
◆ Current state
nabla does forward-mode automatic differentiation in R using dual numbers, returning derivatives exact to machine precision rather than approximated by finite differences. It shipped as dualr in January 2026, then a day later released 0.5.0 under a changed identity: derivatives generalise from a hardcoded second order to arbitrary order through recursive nesting, and the Rcpp and C++ fast paths are deleted so the package is pure R. The current release, 0.7.1, is CRAN resubmission cleanup.
◆ Where it's heading
The 0.5.0 release note states the positioning explicitly: exact machine-precision derivatives at any order, not speed. Removing compiled code to make that claim coherent is an unusual direction, most numerical R packages move the other way, and it commits the package to a niche where correctness beats throughput. The old second-order API survives as deprecated thin wrappers, so the pivot was made without stranding early users. The rapid rename and version jump suggest identity was settled late.
◆ Prediction
Expect CRAN acceptance to be followed by work on the optimiser and MLE integration paths, where arbitrary-order derivatives have the clearest use.
