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 mlr3viz?

mlr3viz keeps the ecosystem's plots working while the plots themselves move out

mlr3viz supplies autoplot methods across mlr3 objects — learners, resample and benchmark results, tuning instances, ensemble feature-selection results. Recent releases are mostly defensive: suppressing ggplot2::fortify() warnings on ROC and PRC curves, pinning legend order so plots are deterministic across ggplot2 environments, and tracking mlr3 1.7.2. A visible piece of scope also left, with the LearnerSurvCoxPH plot moving to mlr3proba.

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.

mlr3viz keeps the ecosystem's plots working while the plots themselves move out

◆ Current state

mlr3viz supplies autoplot methods across mlr3 objects — learners, resample and benchmark results, tuning instances, ensemble feature-selection results. Recent releases are mostly defensive: suppressing ggplot2::fortify() warnings on ROC and PRC curves, pinning legend order so plots are deterministic across ggplot2 environments, and tracking mlr3 1.7.2. A visible piece of scope also left, with the LearnerSurvCoxPH plot moving to mlr3proba.

◆ Where it's heading

The package is being narrowed toward generic plotting infrastructure while learner-specific plots migrate to the packages that own those learners. What it does add is access rather than new charts — passing parameters through to precrec::autoplot(), better hints when the wrong autoplot type is requested, and a confidence-interval plot for mlr3inferr. Determinism across ggplot2 versions has become a recurring concern, which is what happens when a visualization package is depended on by documentation and tests.

◆ Prediction

Following the Cox proportional-hazards precedent, further learner-specific plots are likely to move to their owning packages, leaving mlr3viz with the cross-cutting result objects.
