metatools — R package from the pharmaverse project

pharmaverse.github.io/metatools ↗

SDTM supplemental-qualifier merging got sturdier, then the package went quiet for two years.

◆Current state
metatools provides the utilities that build and check SDTM and ADaM datasets against their metadata in the pharmaverse. The 0.1.6 release in July 2024 is the substantive one: combine_supp() learned to handle zero-row supplemental data, to refuse QNAM columns already present in the source, and to route multiple QNAM values to the same IDVAR, alongside enhanced controlled-terminology checks and record-uniqueness verification. Nothing has shipped since.
◆Where it's heading
The package's development has been concentrated on one function, combine_supp(), which is where the messy realities of supplemental qualifiers surface — whitespace in join keys, empty supp datasets, colliding names. 0.1.6 also drew three first-time contributors, which is the healthiest signal in the history, but no release has followed. Sibling packages have meanwhile been dropping metatools as a dependency.
◆Prediction
Without a release in two years the package looks stable rather than active; the plausible trigger is a controlled-terminology or dplyr change that forces the checks to be updated.

◆Recent moves

    combine_supp() hardened; controlled-terminology checks extended

    Zero-row supplemental data is accepted, QNAM columns already in the source are rejected outright, and multiple QNAM values can target the same IDVAR. check_ct_data() is extended and record uniqueness by key is now verified — the checks that catch a bad dataset before it reaches a submission.

    0.1.4 Update to dplyr and small bug fixes

    combine_supp() trims whitespace before merging, fixing joins that silently failed on padded keys, and get_bad_ct() arrives to surface controlled-terminology violations. The dplyr compatibility work is routine; the whitespace fix is the one that quietly changes results.

    0.1.1 first CRAN release

    The first CRAN release, assembled from a long run of PRs covering build_from_derived(), label handling, subgroup fixes and clearer controlled-terminology error messages. It also switched to depending on metacore from CRAN, settling the package's place in the pharmaverse stack.
