Causal Analysis of Observational Time-to-Event Data

Target trial emulation held steady by dependency maintenance, not new methods.

Current state
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.
Where it's heading
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.
Prediction
Further releases will most likely be triggered by upstream dependency changes; the entries give no signal on when methodological work resumes.

Recent moves

    Documentation references to the archived parglm removed

    Cleanup finishing the parglm removal that 0.0.4.9 began, three months earlier. The body repeats 0.0.4.9's summary line, but the actual change here is documentation only.

    parglm dependency dropped after CRAN archiving

    The release that actually removes parglm, whose CRAN archiving threatened the package's own availability. A dependency change users inherit whether or not they used that fitting path.

    Test fixes for updated testthat, plus link updates

    A same-week follow-up to 0.0.4.7 covering a moved URL. Test-suite upkeep with no user-visible effect.

    Compatibility fixes ahead of testthat 3.3.0

    Test corrections contributed upstream before a testthat release. Representative of how much of this package's release traffic originates outside it.

    Tests updated for duckdb 1.3.0 sampling; R 4.1 now required

    The second duckdb sampling adjustment in four months, plus an R floor raise for native pipe support. The duckdb dependency reliably generates a release per minor version.

    Tests updated for duckdb 1.2.0 sampling changes

    The first of the duckdb sampling fixes, bundled with CRAN check corrections. Sets the maintenance pattern that runs through the rest of the window.
