A side-by-side editorial comparison of chromer and DoseFinding — release velocity, themes, recent moves, and the top alternatives to consider.
chromer vs DoseFinding: 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 DoseFinding?
New stewardship at openpharma, then two releases adding the methods MCP-Mod was missing
DoseFinding implements MCP-Mod and related dose-response methodology for clinical trial design and analysis. In 2024 it changed hands — Marius Thomas took over as maintainer, Novartis was recorded as copyright holder and funder, and the package moved to the openpharma GitHub organisation with roxygen documentation and a proper NEWS file. The two releases since have added substantive methodology: model averaging for dose-response fitting in 1.3-1, and conditional and predictive power for interim analyses in 1.4-1.

◆ 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.

New stewardship at openpharma, then two releases adding the methods MCP-Mod was missing
◆ Current state
DoseFinding implements MCP-Mod and related dose-response methodology for clinical trial design and analysis. In 2024 it changed hands — Marius Thomas took over as maintainer, Novartis was recorded as copyright holder and funder, and the package moved to the openpharma GitHub organisation with roxygen documentation and a proper NEWS file. The two releases since have added substantive methodology: model averaging for dose-response fitting in 1.3-1, and conditional and predictive power for interim analyses in 1.4-1.
◆ Where it's heading
The pattern before the handover was maintenance — R-devel compliance, a bug fix, a link. After it, each release carries a named methodological addition with an acknowledged contributor, plus documentation to match: a longitudinal analysis vignette shipped alongside the interim power work. Housekeeping continues underneath, mostly clearing deprecated ggplot2 interfaces, aes_string in one release and qplot in the next.
◆ Prediction
Given the last two releases each added one method with a supporting vignette, expect the next to follow the same shape. Both additions so far extend the package beyond fixed dose-response fitting, so adaptive and interim methodology is the more likely direction.
