What is chromote?

chromote turned the browser itself into a pinned, downloadable dependency.

chromote drives headless Chrome from R over the DevTools Protocol and underpins the R screenshot and app-testing stack. The visible history is shaped almost entirely by Chrome's own changes: old headless mode removed, DevTools URLs moved, viewport APIs deprecated. Version 0.5.0 answered that by letting chromote fetch and pin specific Chrome builds itself.

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.

chromote turned the browser itself into a pinned, downloadable dependency.

◆ Current state

chromote drives headless Chrome from R over the DevTools Protocol and underpins the R screenshot and app-testing stack. The visible history is shaped almost entirely by Chrome's own changes: old headless mode removed, DevTools URLs moved, viewport APIs deprecated. Version 0.5.0 answered that by letting chromote fetch and pin specific Chrome builds itself.

◆ Where it's heading

The package has moved from reacting to Chrome upgrades to controlling them. The 0.3.0 and 0.4.0 pair tracked the headless-mode transition by first adding an option and then flipping the default; 0.5.0 removed the need to track it at all by managing versioned binaries through Chrome for Testing. Alongside that, the session API keeps accumulating helpers that collapse multi-step DevTools call sequences, such as $go_to() and $set_viewport_size().

◆ Prediction

The version-management features shipped marked experimental, so the likely next step is stabilizing that API and extending the session helpers that wrap common DevTools sequences.

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.
