geodist vs grex
A side-by-side editorial comparison of geodist and grex — release velocity, themes, recent moves, and the top alternatives to consider.
geodist vs grex: at a glance
What is geodist?
geodist stays dependency-free and fast, and warns you when 'cheap' distances stop being honest.
geodist computes geodesic distances between coordinate pairs in C with no dependencies, offering several measures that trade accuracy for speed — including a 'cheap' approximation used by default. The API is small and largely finished; 0.1.0 added geodist_min() for nearest-match lookups and 0.1.1 is a compiler warning fix.
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.

geodist stays dependency-free and fast, and warns you when 'cheap' distances stop being honest.
◆ Current state
geodist computes geodesic distances between coordinate pairs in C with no dependencies, offering several measures that trade accuracy for speed — including a 'cheap' approximation used by default. The API is small and largely finished; 0.1.0 added geodist_min() for nearest-match lookups and 0.1.1 is a compiler warning fix.
◆ Where it's heading
Development has been about making the speed-accuracy trade visible rather than hiding it. The 0.0.6 release added messages telling users to pick a different measure once the default cheap approximation is applied beyond 100km, where its error stops being negligible. Around that, the work is input handling — tibble support, better lon/lat column matching, vector inputs — and hardening the C code. It is a package that treats being small and correct as the feature.
◆ Prediction
Expect continued low-frequency maintenance: compiler warnings and geodesic source updates account for three of the last six releases, and the function surface has grown by only two entries in five years.
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.
