A side-by-side editorial comparison of admiralvaccine and webchem — release velocity, themes, recent moves, and the top alternatives to consider.
Vaccine ADaM templates exist and are maintained, but development has slowed to housekeeping.
admiralvaccine provides vaccine-specific ADaM templates and vignettes — ADCE, ADFACE, ADIS, ADSL — on top of admiral. The last two releases contain no functional change at all: 0.5.0 is maintainer handover, template fixes and lint config, and 0.6.0 is CRAN documentation compliance plus an ecosystem-wide Ask AI widget. Real work was last visible in 0.4.0's criterion-flag deprecation.
Adding chemical databases with one hand while public ones close programmatic access with the other.
webchem is the R interface to public chemical data — retrieving identifiers, properties and structures across roughly a dozen web services. Its release history reads as a running account of which of those services still allow automated access. Version 1.3.0 removed two functions outright because their sources withdrew: ChemIDplus was retired by the NLM, and PAN stopped supporting programmatic access. Version 1.3.1 continues the pattern, updating URLs that stopped working and noting that ChemSpider InChIKey validation now requires an API key like the rest of that provider's endpoints.

The package has moved from building out vaccine domains to keeping them on CRAN. Each release tracks whatever admiral changed upstream and clears whatever CRAN flagged, and the changelogs have shifted from derivation notes to merged-PR lists. Maintainer churn in 0.5.0 is the clearest sign that this is a maintenance-mode package inside an otherwise active ecosystem.
The next release most likely continues the pattern — dependency and documentation alignment with admiral core plus deprecation follow-through — unless a new vaccine reporting requirement forces domain work.

Its release history reads as a running account of which of those services still allow automated access.

Two opposing forces run through these entries. The package keeps widening its coverage — ChEMBL in 1.2.0, LIPID MAPS and SwissLipids identifiers via Wikidata, structure images, Mol export — while the open, unauthenticated end of the chemical web keeps contracting. The other consistent thread is interface harmonisation: successive releases have converged the get_* functions on the same query and from arguments, tibble returns, and CAS reformatting, so the package feels like one interface rather than a dozen wrappers.
Expect further defunct functions and URL repairs as more providers move behind keys or shut down, alongside occasional additions of sources that remain open. The entries show no sign of a general credential-management layer, which is what a package facing this trend would eventually need.
