mlr3proba is shedding weight as its survival work moves into sibling packages
A side-by-side editorial comparison of comtradr and modelbased — release velocity, themes, recent moves, and the top alternatives to consider.
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.
modelbased is turning marginal effects into a full contrast grammar
modelbased computes marginal means, contrasts, and slopes from fitted models, and it ships every one to two months with a consistent shape: new comparison types, broader model support, and steady renaming toward clearer vocabulary. The recent arc runs from marginal effects inequality measures through inequality ratios to an omnibus global test and a post_process argument for multi-step comparisons. Argument names have been settled along the way, with trend becoming slope and an alias left behind.

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.
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.

The package is building a compositional vocabulary rather than a fixed menu — contrasts of average slopes, contrasts across two numeric predictors, inequality summaries across all outcome categories, and now user-supplied post-processing of comparisons. Support quietly widens underneath, covering nestedLogit, brms finite mixtures, and offsets under population and average estimation. Plotting gets attention in proportion to how often these results are presented rather than tabulated, including collapse_by_group() for showing averaged raw data under mixed-model fits.
With post_process and omnibus tests both landed, the likely next step is making these composed comparisons easier to report — formatting or plotting methods for the multi-step results rather than new comparison types.
