What is grex?

grex is a lookup table with a version number — it ships when the annotation moves.

grex converts the deprecated Ensembl gene IDs found in GTEx data into current gene symbols and identifiers, using org.Hs.eg.db as its reference. Its value is entirely in that bundled reference data, so a release either refreshes the mapping or does nothing to it. The 2025 release does nothing to it: GitHub Actions for the docs site, a check-note fix, and a smaller vignette.

What is rjwsacruncher?

A thin R wrapper around a Java seasonal-adjustment tool, slowly absorbing the setup work.

rjwsacruncher drives JDemetra+'s JWSACruncher from R, handling parameter files and batch runs of seasonal adjustment workspaces. Recent releases have shifted from wrapping the executable to managing its installation: 0.2.3 adds a downloader for JDemetra+ itself, a check that a given directory really contains the cruncher binary, and tolerance for users pointing at the executable instead of its bin directory.

grex is a lookup table with a version number — it ships when the annotation moves.

◆ Current state

grex converts the deprecated Ensembl gene IDs found in GTEx data into current gene symbols and identifiers, using org.Hs.eg.db as its reference. Its value is entirely in that bundled reference data, so a release either refreshes the mapping or does nothing to it. The 2025 release does nothing to it: GitHub Actions for the docs site, a check-note fix, and a smaller vignette.

◆ Where it's heading

The annotation refreshes stopped. Between 2017 and 2019 the package tracked org.Hs.eg.db through four versions and added the GTEx V7 identifier set; since then the reference has stood still while the releases turned to packaging. That gap matters more here than it would elsewhere — a stale mapping table silently returns outdated symbols rather than failing, so the package's core asset ages invisibly.

◆ Prediction

Nothing in these entries signals a planned data refresh, and the six-year pattern suggests the next release will again be infrastructure. Users needing current annotations should check which org.Hs.eg.db version is bundled rather than assume the version number reflects it.

A thin R wrapper around a Java seasonal-adjustment tool, slowly absorbing the setup work.

◆ Current state

rjwsacruncher drives JDemetra+'s JWSACruncher from R, handling parameter files and batch runs of seasonal adjustment workspaces. Recent releases have shifted from wrapping the executable to managing its installation: 0.2.3 adds a downloader for JDemetra+ itself, a check that a given directory really contains the cruncher binary, and tolerance for users pointing at the executable instead of its bin directory.

◆ Where it's heading

The work is defensive. Most of each release addresses a way users misconfigure paths or versions — clearer errors, a startup message naming which cruncher version the options select, and a standalone flag on the downloader. The package is absorbing the friction of a Java dependency it does not control.

◆ Prediction

Expect continued compatibility work as JDemetra+ 3.x diverges from 2.x, since the version split is already surfaced as a user-facing option rather than resolved internally.
