admiraldiscovery vs lobstr: at a glance
What is admiraldiscovery?
A lookup index for the admiral family that grows one therapeutic area at a time.
admiraldiscovery is a search aid rather than a code package: it maps ADaM variables to the {admiral} functions that derive them, alongside a listing of conference presentations. Its releases are catalogue updates, not functional changes. The most recent adds variables from {admiralneuro} plus AAGE and NFRLT.
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.

◆ Current state
admiraldiscovery is a search aid rather than a code package: it maps ADaM variables to the {admiral} functions that derive them, alongside a listing of conference presentations. Its releases are catalogue updates, not functional changes. The most recent adds variables from {admiralneuro} plus AAGE and NFRLT.
◆ Where it's heading
Each release absorbs the variable listing of whichever therapeutic-area extension shipped most recently — paediatrics in 0.3.0, metabolic in 0.4.0, neuro in 0.6.0. The package is effectively an index trailing the family's expansion, so its cadence is a proxy for how fast new admiral extensions appear.
◆ Prediction
The next release will most likely fold in variables from whichever admiral therapeutic-area package lands next, together with a refreshed presentation list.

R's object inspector is losing its view of the internals as CRAN closes off the private C API.
◆ Current state

◆ 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.
