What is nert?

nert put fourteen TERN datasets behind one dispatcher and called it stable.

nert is an R client for the TERN data API, reaching its first stable release in May 2026 after a year of milestone-tagged development. Version 1.0.0 exposes eleven functions covering fourteen datasets — SMIPS, ASC, AET, eight SLGA soil attributes, Soil Beta Diversity, Canopy Height and Land Surface Phenology — through a single read_tern(dataset_id, ...) dispatcher plus collect_tern_data() for batch extraction across locations and date ranges. Coverage sits at 83% overall with every reader at 100%.

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.

nert put fourteen TERN datasets behind one dispatcher and called it stable.

◆ Current state

nert is an R client for the TERN data API, reaching its first stable release in May 2026 after a year of milestone-tagged development. Version 1.0.0 exposes eleven functions covering fourteen datasets — SMIPS, ASC, AET, eight SLGA soil attributes, Soil Beta Diversity, Canopy Height and Land Surface Phenology — through a single read_tern(dataset_id, ...) dispatcher plus collect_tern_data() for batch extraction across locations and date ranges. Coverage sits at 83% overall with every reader at 100%.

◆ Where it's heading

The release history is unusual in that most of its tags are not releases: Milestone 1, 2 and 4 were pushed within eight minutes of each other in July 2025 purely as grant reporting and audit markers, with no user-facing content. What the 1.0.0 notes emphasise instead is test discipline — 310 deterministic offline tests, snapshot pins on every TERN bucket path and filename template, and mocked COG reads so R CMD check never touches the network. That is a client built on the assumption that the remote API's URL structure will change underneath it.

◆ Prediction

The notes describe pre-CRAN review polish and itemise remaining check NOTEs in cran-comments.md, so the next move is most likely a CRAN submission rather than additional dataset coverage.

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.
