chromer vs cleanepi: at a glance
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 cleanepi?
cleanepi is in the long tail of bug fixes that follows a 1.0 — and changed maintainers along the way.
cleanepi cleans and standardises epidemiological line list data — dates, subject IDs, missing values, duplicates — and produces a report of what it changed. Since 1.0.0 in mid-2024 the releases have been almost entirely corrective: date-guesser fixes, report structure fixes and matching behaviour corrections. Maintainership passed to Bubacarr Bah in 1.1.2.

◆ 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.
cleanepi
0.0ANALYTICS
cleanepi is in the long tail of bug fixes that follows a 1.0 — and changed maintainers along the way.
◆ Current state
cleanepi cleans and standardises epidemiological line list data — dates, subject IDs, missing values, duplicates — and produces a report of what it changed. Since 1.0.0 in mid-2024 the releases have been almost entirely corrective: date-guesser fixes, report structure fixes and matching behaviour corrections. Maintainership passed to Bubacarr Bah in 1.1.2.
◆ Where it's heading
Work has concentrated on the report object and on making the cleaning functions behave predictably at the edges — case- and whitespace-insensitive missing-value matching, report elements returned as vectors instead of comma-separated strings, an argument to print a single operation's report. The underlying cleaning API has barely moved since 1.0.0, which suggests it is settled.
◆ Prediction
The report interface has been reworked repeatedly across these releases and is the most likely place for further change; the cleaning functions themselves look stable.

A weather-station data client that broke one return type to hand back distances instead of bare IDs.
giscoR
giscoR's 1.0 moved its dataset index into the cache, so new Eurostat releases arrive without a package update.
