admiralneuro vs lobstr: at a glance
What is admiralneuro?
admiralneuro is widening from Alzheimer's PET into general nervous-system findings.
The package launched in September 2025 with amyloid and tau PET analysis for Alzheimer's studies — centiloid computation, five neuro datasets, and ADAPET/ADTPET template programs. The February 2026 update is tagged twice on the same day, 0.2.0 and 0.2.1 carrying the same notes, and adds olfactory testing plus a nervous-system findings template.
What is lobstr?
R's object inspector is losing its view of the internals as CRAN closes off the private C API.
lobstr exposes R's internal object representation — sizes, addresses, reference counts, abstract syntax trees. Its two most recent releases are both driven by R's move to a restricted public C API: 1.1.3 stopped reporting a vector's truelength and reworked the reference indicator into refs:n, and 1.2.0 changed what sxp(expand = "environment") shows in order to stay compliant. 1.2.0 also adds src() for exploring srcref objects.

admiralneuro is widening from Alzheimer's PET into general nervous-system findings.
◆ Current state
The package launched in September 2025 with amyloid and tau PET analysis for Alzheimer's studies — centiloid computation, five neuro datasets, and ADAPET/ADTPET template programs. The February 2026 update is tagged twice on the same day, 0.2.0 and 0.2.1 carrying the same notes, and adds olfactory testing plus a nervous-system findings template.
◆ Where it's heading
Development is moving from one disease area toward a general neuro toolkit: UPSIT smell-identification percentiles now sit alongside PET quantitation, and the ADNV template covers nervous-system findings broadly rather than PET specifically. Internal SDTM test data was retired in favour of pharmaversesdtm, tying the package more tightly to the shared pharmaverse data layer.
◆ Prediction
More assessment-specific compute functions on the UPSIT pattern are the obvious next step, each arriving with a vignette and a template program alongside it.

R's object inspector is losing its view of the internals as CRAN closes off the private C API.
◆ Current state
lobstr exposes R's internal object representation — sizes, addresses, reference counts, abstract syntax trees.

◆ Where it's heading
The package is being rebuilt inside a shrinking window of what R permits. Each release trades some introspection depth for API conformance while trying to keep the diagnostic value intact — showing promise expressions instead of internal frame structures, replacing named with a documented refs scale. Where the constraint does not bite, development continues normally: src() is genuinely new, and the environment-binding fixes remove long-standing errors on for-loop and immediate bindings.
◆ Prediction
Expect further conformance work, since the notes describe it as ongoing, with any remaining non-API-dependent readouts either reworked or dropped as R tightens further.
