exametrika vs nominatimlite: at a glance
What is exametrika?
A test-theory package that grew into a graphical-model toolkit, now spending its releases paying down the API debt that growth created.
exametrika is an R psychometrics package covering IRT, latent class/rank analysis, and biclustering, and it has been shipping features at an unusual clip for a CRAN package. The last two releases stopped adding capability and turned inward: 1.14.0 fixed a documented-but-never-implemented graphical-parameter passthrough, and 1.15.0 landed a full-codebase audit that corrected bugs which silently produced wrong results on missing data and 0-indexed polytomous codes. Argument names, orders, and defaults are now unified across the model functions, with every old name kept working behind a deprecation warning.
What is nominatimlite?
nominatimlite's real work was self-hosting and caching; 0.6.0 is an internal refactor with no API change
nominatimlite is a dependency-light R client for the Nominatim geocoding API, returning results as plain data frames or sf objects. The features that define it landed in 0.4.0 — structured queries, local Nominatim server support, and JSONV2 output — and 0.5.0 added session-scoped caching plus a 1.2-second inter-request delay to stay within the public API's usage policy. 0.6.0 in June 2026 changed no public behaviour.

◆ Current state
exametrika is an R psychometrics package covering IRT, latent class/rank analysis, and biclustering, and it has been shipping features at an unusual clip for a CRAN package. The last two releases stopped adding capability and turned inward: 1.14.0 fixed a documented-but-never-implemented graphical-parameter passthrough, and 1.15.0 landed a full-codebase audit that corrected bugs which silently produced wrong results on missing data and 0-indexed polytomous codes. Argument names, orders, and defaults are now unified across the model functions, with every old name kept working behind a deprecation warning.
◆ Where it's heading
The arc runs from feature sprawl to consolidation. Through 1.9.0-1.13.0 the package added polytomous biclustering plots, nominal and ordinal IRM samplers, a C++ Gibbs core, and Graphical Lasso; the cost was inconsistent interfaces and correctness bugs that only surfaced under audit. The maintainer is also visibly optimizing for two external gatekeepers — CRAN's 10-minute check budget in 1.13.1, an R Journal reviewer in 1.14.0 — which suggests the package is being groomed for formal publication rather than just iterated on.
◆ Prediction
Expect the next release to continue the deprecation cleanup started in 1.15.0, likely retiring some of the old function names that have carried warnings since 1.7.0, with new modelling work paused until the R Journal submission clears.

◆ Current state
nominatimlite is a dependency-light R client for the Nominatim geocoding API, returning results as plain data frames or sf objects. The features that define it landed in 0.4.0 — structured queries, local Nominatim server support, and JSONV2 output — and 0.5.0 added session-scoped caching plus a 1.2-second inter-request delay to stay within the public API's usage policy. 0.6.0 in June 2026 changed no public behaviour.
◆ Where it's heading
The package has settled. Recent effort goes to being a well-behaved API citizen and to internal consistency: 0.6.0 raised the minimum R to 4.1.0 and refactored URL construction, progress handling, coordinate validation and output preparation with AI assistance, explicitly leaving the public API untouched. That refactor is part of a sweep across the same maintainer's packages in the same weeks.
◆ Prediction
With the API surface stable and rate-limiting handled, future releases most likely track upstream Nominatim endpoint changes, as 0.4.0 did for v4.4.0. Nothing in the entries points to new query capabilities.
