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 renv?

renv 1.2 made installs parallel, its biggest performance change in years.

renv provides project-local dependency management for R. The 1.2.0 release rebuilt installation to download and compile concurrently, and the 1.2.x line since has been resolving the correctness problems parallelism exposed — binaries installing ahead of their dependencies, transitive upgrades that were never needed, lockfile paths shifting with the working directory.

A test-theory package that grew into a graphical-model toolkit, now spending its releases paying down the API debt that growth created.

◆ 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.

2.5

renv 1.2 made installs parallel, its biggest performance change in years.

◆ Current state

renv provides project-local dependency management for R. The 1.2.0 release rebuilt installation to download and compile concurrently, and the 1.2.x line since has been resolving the correctness problems parallelism exposed — binaries installing ahead of their dependencies, transitive upgrades that were never needed, lockfile paths shifting with the working directory.

◆ Where it's heading

Work is consolidating around two things: making the parallel installer correct under real dependency graphs, and broadening remote support so private and self-hosted sources resolve properly. The most recent release translates self-hosted GitLab remotes into the syntax pkgdepends actually understands.

◆ Prediction

Expect continued fixes to install ordering and remote resolution rather than another performance overhaul, since the parallel path is new enough to keep surfacing ordering bugs.
