What is gcube?

gcube's recent releases are all packaging metadata, not simulation code

gcube simulates biodiversity data cubes — generating occurrence points, sampling them under configurable detection bias, and designating them to a grid — as a testbed for the B-Cubed project's indicator tooling. The visible release history is almost entirely metadata and release-automation work: Zenodo grant IDs, ROR URL fixes, publisher fields, funder and rights-holder descriptions. The simulation functionality itself is not what these entries are about.

What is rmediation?

RMediation shipped a three-normal CDF, then found it was silently wrong.

RMediation is a long-standing CRAN package for confidence intervals on mediated effects, now built on an S7 class hierarchy. Over eight weeks it added ProductNormal3 for serial indirect effects of the form a1*a2*b, folded the engine into the existing pprodnormal naming family, and then replaced that engine outright after finding it returned wrong probabilities without warning. The dev branch is at 1.7.0; CRAN still serves 1.6.1.

gcube's recent releases are all packaging metadata, not simulation code

◆ Current state

gcube simulates biodiversity data cubes — generating occurrence points, sampling them under configurable detection bias, and designating them to a grid — as a testbed for the B-Cubed project's indicator tooling. The visible release history is almost entirely metadata and release-automation work: Zenodo grant IDs, ROR URL fixes, publisher fields, funder and rights-holder descriptions. The simulation functionality itself is not what these entries are about.

◆ Where it's heading

The February 2026 cluster reads as a package wiring up its archival identity rather than developing: four releases in four days, one of them explicitly a test of the GitHub release path. That is characteristic of research software preparing to be cited — a Zenodo DOI, correct funder attribution and a checklist-compliant description are the deliverables when the funder requires them. Substantive work on mapping functions and grid designation appears earlier and only through tutorial fixes.

◆ Prediction

With the Zenodo integration and metadata now settled, expect attention to return to the simulation functions themselves, most likely driven by what the sibling indicator packages need to test against.

RMediation shipped a three-normal CDF, then found it was silently wrong.

◆ Current state

RMediation is a long-standing CRAN package for confidence intervals on mediated effects, now built on an S7 class hierarchy. Over eight weeks it added ProductNormal3 for serial indirect effects of the form a1*a2*b, folded the engine into the existing pprodnormal naming family, and then replaced that engine outright after finding it returned wrong probabilities without warning. The dev branch is at 1.7.0; CRAN still serves 1.6.1.

◆ Where it's heading

The package is moving from a hand-rolled numerical layer to one that checks itself: the new default integrator escalates its node count until successive rules agree, warns when it hits the cap instead of returning a number, and exposes a diagnostics argument for the convergence estimate. The correctness fix went to dev ahead of the CRAN window rather than being held for it, which suggests wrong-answer bugs are treated as release-blocking regardless of cadence. Serial mediation is where the new surface area is concentrated.

◆ Prediction

1.7.0 exists specifically to land before CRAN's 2026-08-21 update window, so the next move is a CRAN submission promoting it to main; whether hcubature survives past that as a cross-check option is the open question.
