lobstr vs pharmaversesdtm: at a glance
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.
What is pharmaversesdtm?
pharmaversesdtm is the test-data layer every pharmaverse package now builds against.
The package ships example SDTM datasets and has grown one therapeutic area at a time — ophthalmology, oncology response criteria, vaccines, metabolic, neurology, and now lymphoma under Lugano 2014. Sibling packages keep moving their internal test data here, so its release notes double as a record of what the rest of the pharmaverse is building.

◆ Current state
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.
◆ 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.
pharmaversesdtm
0.0ANALYTICS
pharmaversesdtm is the test-data layer every pharmaverse package now builds against.
◆ Current state
The package ships example SDTM datasets and has grown one therapeutic area at a time — ophthalmology, oncology response criteria, vaccines, metabolic, neurology, and now lymphoma under Lugano 2014. Sibling packages keep moving their internal test data here, so its release notes double as a record of what the rest of the pharmaverse is building.
◆ Where it's heading
Two kinds of work alternate: adding domains and biomarkers for a new indication, and making the existing data easier to reach — CSV copies under inst/extdata for non-R programmers, a datasets preview vignette, reference pages categorised by therapeutic area, variable-by-variable breakdowns. Consistency fixes against CDISC terminology and SDTM guidelines run through every release.
◆ Prediction
New therapeutic areas will keep arriving in step with the admiral extension packages that need them; the neurology and metabolic datasets landed just ahead of admiralneuro and admiralmetabolic needing them, and lymphoma looks like the next in that sequence.
