compositional.mle
An MLE package rebuilt around composable solvers, then renamed to match.
A side-by-side editorial comparison of kwb.geosalz and TrialEmulation — release velocity, themes, recent moves, and the top alternatives to consider.
A research-project workflow package where the interesting work is in the plumbing.
kwb.geosalz documents the data workflows for GeoSalz, a groundwater salinisation project run by Kompetenzzentrum Wasser Berlin, packaging retrieval, checking and plotting steps as reproducible R code. The current release replaces an SFTP dependency with curl and reports listing files on the SFTP server running 50 to 100 times faster. Earlier releases added data-availability workflows against Berlin's open water portal and functions for well-field abstraction figures.
Target trial emulation held steady by dependency maintenance, not new methods.
TrialEmulation implements target trial emulation from observational data, using duckdb to handle the expanded per-period datasets that approach generates. Every release in the visible window is upkeep: two consecutive releases removing the archived parglm dependency, two fixing tests against testthat updates, and two tracking duckdb sampling changes. No methodological work appears in the feed since before February 2025.

Releases track the project's own data-collection reality rather than a software roadmap: new data source appears, a workflow is added; a transfer library becomes a liability, it is swapped out. The measurement-chain pipeline is the recurring subject, appearing in plotting fixes at 0.7.1 and the transport rewrite at 0.7.2. Cadence is roughly annual and the changelog is written for project members, which makes external readability secondary by design.
Expect the next release to follow the measurement-chain data as it accumulates, most likely more plotting or availability-checking work rather than new infrastructure.

No methodological work appears in the feed since before February 2025.
The package is being kept installable rather than extended. Its dependency surface, duckdb for storage, parglm for fitting, testthat for checks, generates most of the release traffic, and CRAN archiving parglm forced two separate releases three months apart to fully excise it. The version numbering, still in the 0.0.4.x range after years, suggests the maintainers do not consider the API settled enough to promote.
Further releases will most likely be triggered by upstream dependency changes; the entries give no signal on when methodological work resumes.
