What is admiral?

admiral spent its last cycle making complex derivations documentable rather than adding more of them.

admiral is the pharmaverse's ADaM dataset derivation toolkit — a large library of derive_* functions for building analysis datasets from SDTM. The 1.2.0 and 1.3.0 releases added new derivation functions and then a substantial documentation overhaul: argument defaults now appear in the help text and complex functions carry titled, described examples. 1.3.1 was a hotfix for links and the search index.

What is tulpa?

The 0.0.x train stops at CRAN: tulpa's engine ships to the ecosystem it already anchors.

tulpa is the C++/R Bayesian spatial inference engine sitting under gcol33's family of ecological occupancy packages, tagging 0.0.x releases several times a week. 0.1.0 is its first CRAN release, and the notes state outright that the engine surface is unchanged from 0.0.198 — the work is packaging discipline: local T bindings rebound to n_t/n_times, OpenMP teams capped under R CMD check, the pkgdown deploy narrowed, an aspell dictionary added. The window behind it splits between the S3 generics conversion and numerical-correctness work in the nested-Laplace grid.

ANALYTICS
0.0

admiral spent its last cycle making complex derivations documentable rather than adding more of them.

◆ Current state

admiral is the pharmaverse's ADaM dataset derivation toolkit — a large library of derive_* functions for building analysis datasets from SDTM. The 1.2.0 and 1.3.0 releases added new derivation functions and then a substantial documentation overhaul: argument defaults now appear in the help text and complex functions carry titled, described examples. 1.3.1 was a hotfix for links and the search index.

◆ Where it's heading

The direction is toward usability of an already-large API rather than growth of it. 1.1.0 rewrote error messaging to be user-facing, 1.2.0 added flexibility to duplicate handling across several functions via check_type, and 1.3.0 invested in the structured-example documentation that the rdx_roclet work in {admiraldev} made possible. The two packages move together.

◆ Prediction

With the documentation infrastructure in place, expect the remaining complex derivation functions to be brought up to the structured-example standard, and new therapeutic-area work to keep landing in the extension packages rather than the core.

7.5

The 0.0.x train stops at CRAN: tulpa's engine ships to the ecosystem it already anchors.

◆ Current state

tulpa is the C++/R Bayesian spatial inference engine sitting under gcol33's family of ecological occupancy packages, tagging 0.0.x releases several times a week. 0.1.0 is its first CRAN release, and the notes state outright that the engine surface is unchanged from 0.0.198 — the work is packaging discipline: local T bindings rebound to n_t/n_times, OpenMP teams capped under R CMD check, the pkgdown deploy narrowed, an aspell dictionary added. The window behind it splits between the S3 generics conversion and numerical-correctness work in the nested-Laplace grid.

◆ Where it's heading

Two moves in nine days point at the same destination: the generics conversion made tulpa extensible by downstream packages, and CRAN admission makes it installable by them. The current cadence — several tags a week, some existing only to record a measurement that produced no code change — does not survive CRAN's submission overhead, so the release rhythm has to slow whether or not the project intends it. The correctness work still clusters on the joint nested-Laplace driver, and 0.1.0 extends the same diagnostics habit with .NL_AXIS_SD_REASONS, a closed vocabulary for an outer axis whose grid does not contain its own posterior mode.

◆ Prediction

Expect tulpaObs to follow tulpa onto CRAN, since it is the consumer whose registrations the engine has spent this window unblocking, and expect the version line to move in larger, less frequent steps now that each one carries a submission.
