What is chromer?

A chromosome-count database client that only ever ships when the upstream API moves.

chromer is a thin R client for the Chromosome Counts Database. Every release in the past three years is maintenance: a new maintainer and licence change in 0.3, test-skipping when the upstream service is down in 0.4, and two separate releases whose entire content is that the database's URL changed again. The current 0.10 points at ccdb.tau.ac.il/services/.

What is osmextract?

osmextract stopped throwing your OpenStreetMap downloads away at the end of every session.

osmextract downloads OpenStreetMap extracts from Geofabrik, BBBike and openstreetmap.fr and translates them into sf objects via GDAL. The 0.6.0 release moved its download cache from `tempdir()` to a persistent `tools::R_user_dir()` location and raised the R floor to 4.1.0 to get it. It also made spatial `place` inputs self-clipping: pass an sf or bbox object and the boundary is now set to match, so only the relevant slice of a country-sized extract is processed.

A chromosome-count database client that only ever ships when the upstream API moves.

◆ Current state

chromer is a thin R client for the Chromosome Counts Database. Every release in the past three years is maintenance: a new maintainer and licence change in 0.3, test-skipping when the upstream service is down in 0.4, and two separate releases whose entire content is that the database's URL changed again. The current 0.10 points at ccdb.tau.ac.il/services/.

◆ Where it's heading

The package is functionally complete and externally driven — its release cadence is a record of the CCDB's hosting history rather than of any development plan. The defensive work in 0.4, which added an internal check for whether the database is down and skips tests accordingly, shows the maintainer treating upstream instability as the permanent condition rather than an incident.

◆ Prediction

The next release will most likely be triggered by another CCDB endpoint or format change; nothing in the history suggests new functionality is planned.

osmextract stopped throwing your OpenStreetMap downloads away at the end of every session.

◆ Current state

osmextract downloads OpenStreetMap extracts from Geofabrik, BBBike and openstreetmap.fr and translates them into sf objects via GDAL. The 0.6.0 release moved its download cache from `tempdir()` to a persistent `tools::R_user_dir()` location and raised the R floor to 4.1.0 to get it. It also made spatial `place` inputs self-clipping: pass an sf or bbox object and the boundary is now set to match, so only the relevant slice of a country-sized extract is processed.

◆ Where it's heading

Two threads run through every release. One is chasing GDAL — SQL syntax adjusted for 3.10, ogr2ogr options fixed for 3.9, and an `osmconf.ini` that 0.6.0 finally keeps automatically in sync with whatever sf or GDAL provides rather than shipping a snapshot. The other is the road-network extraction added experimentally in 0.3.1, which has been quietly accumulating real routing semantics since: `access = no` links retained when the mode-specific tag permits them, a `oneway` column by default for driving, and `motor_vehicle` always included.

◆ Prediction

Given that `oe_get_network()` has gained transport-mode detail in three separate releases while remaining flagged as experimental, the next substantive work is most likely there — either more modes or a formal exit from experimental status.
