chromer vs random.cdisc.data: 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 random.cdisc.data?
Synthetic CDISC data generation that has been quiet since early 2024.
random.cdisc.data generates synthetic CDISC-format clinical trial datasets, used across the insightsengineering and teal packages as test and demo data. The last substantive release, 0.3.15 in March 2024, made cached-data rebuilds incremental and corrected an ETHNIC factor level. Everything older in this feed is release automation.

◆ 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.
random.cdisc.data
0.0ANALYTICS
Synthetic CDISC data generation that has been quiet since early 2024.
◆ Current state
random.cdisc.data generates synthetic CDISC-format clinical trial datasets, used across the insightsengineering and teal packages as test and demo data. The last substantive release, 0.3.15 in March 2024, made cached-data rebuilds incremental and corrected an ETHNIC factor level. Everything older in this feed is release automation.
◆ Where it's heading
Activity has thinned to one real release in the visible window, surrounded by version bumps and workflow propagation. The 0.3.15 work is maintenance-shaped — dependency floors, a data typo, faster vignette rebuilds — which is what a fixture package looks like once downstream packages depend on its output staying unchanged.
◆ Prediction
Further releases are likely to stay corrective, since the package's value to teal and tern depends on its generated datasets remaining stable rather than growing.

giscoR's 1.0 moved its dataset index into the cache, so new Eurostat releases arrive without a package update.
