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 pathfindR?

pathfindR dropped Java from its subnetwork search and rebuilt it in C++

pathfindR runs active-subnetwork-oriented pathway enrichment on gene expression results. Version 3.0.0 re-implemented the greedy, simulated-annealing and genetic search algorithms in R and C++ through Rcpp, removing the Java dependency the package had carried since its early releases, and renamed three exported functions in the process. The two patches since have been consolidation: 3.0.1 fixed signed integer overflow in the new C++ hash function flagged by gcc-UBSAN and clang-UBSAN on CRAN, and 3.0.2 repaired tests after a companion data package changed a dataset structure.

◆ 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.

pathfindR dropped Java from its subnetwork search and rebuilt it in C++

◆ Current state

pathfindR runs active-subnetwork-oriented pathway enrichment on gene expression results. Version 3.0.0 re-implemented the greedy, simulated-annealing and genetic search algorithms in R and C++ through Rcpp, removing the Java dependency the package had carried since its early releases, and renamed three exported functions in the process. The two patches since have been consolidation: 3.0.1 fixed signed integer overflow in the new C++ hash function flagged by gcc-UBSAN and clang-UBSAN on CRAN, and 3.0.2 repaired tests after a companion data package changed a dataset structure.

◆ Where it's heading

The dependency surface has been shrinking for two years and Java was the last heavy one. 2.4.0 removed magick, KEGGgraph and KEGGREST by moving KEGG visualization onto ggkegg; 2.7.0 pushed org.Hs.eg.db from Imports to Suggests under CRAN policy, with functions degrading to defaults when it is absent; 3.0.0 finished the job on the search engine itself. The corresponding cost is now visible in 3.0.1: owning the algorithms in C++ means owning their undefined-behaviour reports too.

◆ Prediction

Expect the near-term releases to keep hardening the Rcpp search code against sanitizer findings and to verify GA parity with the legacy JAR, since 3.0.0 claimed numerically identical results only for the greedy and simulated-annealing methods.

Frequently asked questions

What is the difference between exametrika and pathfindR?

Both compete on the same themes — r-package — within Infra & APIs. exametrika and pathfindR are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.

Is exametrika better than pathfindR?

Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. exametrika and pathfindR are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
