What is comtradr?

comtradr's 1.0 line is a long tail of patches against a brittle UN trade API.

comtradr wraps the UN Comtrade API for international trade data in R, handling authentication, reference tables, caching and bulk downloads. The entire visible window is the 1.0 patch series: six releases, most of them repairs. The substantive additions are a variable-metadata reference table and automatic request splitting.

What is mlr3measures?

mlr3measures is systematically retrofitting sample weights across every metric

mlr3measures is the metric library behind mlr3. Recent releases follow two threads: adding measures — linex, pinball, Mu AUC, gmean, gpr, mcc — and retrofitting sample_weights support across the existing ones, reaching AUC and the confusion-matrix family in 1.3.0. Along the way 1.1.0 deprecated four regression measures and corrected the bias definitions.

2.5

comtradr's 1.0 line is a long tail of patches against a brittle UN trade API.

◆ Current state

comtradr wraps the UN Comtrade API for international trade data in R, handling authentication, reference tables, caching and bulk downloads. The entire visible window is the 1.0 patch series: six releases, most of them repairs. The substantive additions are a variable-metadata reference table and automatic request splitting.

◆ Where it's heading

The work is defensive, shaped by the API's constraints rather than by a roadmap. The 1.0.6 fix is representative: Comtrade rejects URLs longer than about 2000 characters, so the package now detects that before the request and transparently splits and recombines it. Running alongside is steady dependency hygiene, most recently swapping poorman for dplyr ahead of a CRAN archival.

◆ Prediction

The release pattern points to more of the same, with error-message and edge-case repairs as users hit new API limits, rather than new endpoints.

mlr3measures is systematically retrofitting sample weights across every metric

◆ Current state

mlr3measures is the metric library behind mlr3. Recent releases follow two threads: adding measures — linex, pinball, Mu AUC, gmean, gpr, mcc — and retrofitting sample_weights support across the existing ones, reaching AUC and the confusion-matrix family in 1.3.0. Along the way 1.1.0 deprecated four regression measures and corrected the bias definitions.

◆ Where it's heading

The library is maturing rather than growing: weighted evaluation and observation-wise loss functions are being brought to metrics that already existed, which is what downstream weighted-resampling and per-observation analysis need. The deprecations suggest the maintainers are willing to remove measures they consider ill-defined rather than keep them for compatibility.

◆ Prediction

Expect sample_weights and observation-wise variants to reach the remaining measures that lack them.
