admiralpeds vs lobstr

admiralpeds vs lobstr: at a glance
What is admiralpeds?
admiralpeds has shipped nothing but documentation for four releases running.
The paediatric extension to admiral provides growth-parameter derivations against WHO and CDC metadata. Across its last four releases the notes contain no new functions and no changed derivations — the entries are vignettes, website theming, badges, an LLM documentation widget, lint configuration and a roclet migration to admiraldev.
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.

admiralpeds has shipped nothing but documentation for four releases running.
◆ Current state
The paediatric extension to admiral provides growth-parameter derivations against WHO and CDC metadata. Across its last four releases the notes contain no new functions and no changed derivations — the entries are vignettes, website theming, badges, an LLM documentation widget, lint configuration and a roclet migration to admiraldev.
◆ Where it's heading
Development has moved almost entirely into the shared pharmaverse infrastructure: subject test data went out to pharmaversesdtm, lint configuration and the custom admiral roclets moved to admiraldev, and the website now follows the same PR-triggered build workflow as its sibling packages. What is left in the package itself is the growth derivations, which have not changed in these entries.
◆ Prediction
On this evidence the growth-derivation surface is considered complete; the next release is more likely to track an admiraldev or admiral change than to add a derivation.

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.
