geomander vs grex: at a glance
What is geomander?
A redistricting toolkit that grows mostly by wiring in new public data sources
geomander provides geographic tools for redistricting analysis in R — matching and aggregating across block, VTD and district geometries, spatial diagnostics, and download helpers for the datasets the field relies on. Recent work splits between data access, with fetchers added for Jeffrey B. Lewis's historical congressional districts and RPV Near Me, and performance, with 2.5.0 delivering large speed gains in geo_match().
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.

◆ Current state
geomander provides geographic tools for redistricting analysis in R — matching and aggregating across block, VTD and district geometries, spatial diagnostics, and download helpers for the datasets the field relies on. Recent work splits between data access, with fetchers added for Jeffrey B. Lewis's historical congressional districts and RPV Near Me, and performance, with 2.5.0 delivering large speed gains in geo_match().
◆ Where it's heading
The package is consolidating as infrastructure rather than expanding its analytical surface. Each release either adds a source of redistricting data that users would otherwise download by hand, or makes the core geographic matching operations faster and more correct — the normalized global Moran's I correction and the block-level geometry mismatch fix both fall in the second category. geo_match() being the target of the most recent release confirms where the hot path is.
◆ Prediction
With geo_match() now optimised, the remaining friction is in the download helpers, several of which have needed repair after upstream changes; expect the next release to consolidate or harden those fetchers rather than add analysis functions.
grex
0.0ANALYTICS
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.
