BayLum vs pathfindR: at a glance
What is BayLum?
Bayesian luminescence dating that finally replaced its folder-structure input format.
BayLum runs Bayesian age models for luminescence and combined OSL/C-14 dating on top of JAGS. The 2024 release rebuilt the front end: a single create_DataFile() replaces the separate single-grain and multi-grain generators, reads BIN/BINX and XSYG directly, and takes a YAML config in place of the old prescribed folder layout. Since then the work has been CRAN compliance and documentation.
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.

Bayesian luminescence dating that finally replaced its folder-structure input format.
◆ Current state
BayLum runs Bayesian age models for luminescence and combined OSL/C-14 dating on top of JAGS. The 2024 release rebuilt the front end: a single create_DataFile() replaces the separate single-grain and multi-grain generators, reads BIN/BINX and XSYG directly, and takes a YAML config in place of the old prescribed folder layout. Since then the work has been CRAN compliance and documentation.
◆ Where it's heading
Two long-running threads have converged: making JAGS runs survivable (parallel methods, halved MCMC memory, injectable custom models) and making the inputs survivable (YAML config, consistency checks, auto-detected sample names). With the deprecated generators on their way out, the next phase is removal rather than addition. Release cadence is roughly annual and slowing.
◆ Prediction
The deprecated Generate_DataFile(), Generate_DataFile_MG() and LT_RegenDose() are the obvious next casualties; a release that drops them would be the first breaking change since the YAML rework.

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.

◆ 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 BayLum and pathfindR?
Both compete on the same themes — r-package — within Infra & APIs. BayLum 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 BayLum better than pathfindR?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. BayLum and pathfindR are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
