What is asar?

A NOAA report-template generator being debugged by the workshops that teach it.

asar generates standardized stock assessment report skeletons, with create_template() as the function everything else orbits. The visible release history is short and entirely reactive: two rounds of fixes to template customization and rerendering, then a documentation release moving the project's authoring guidelines onto the package website as living articles. Nothing in the window adds capability.

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.

asar vs BayLum: editorial side-by-side

A
asar
INFRA · APIS
0.0

A NOAA report-template generator being debugged by the workshops that teach it.

◆ Current state

asar generates standardized stock assessment report skeletons, with create_template() as the function everything else orbits. The visible release history is short and entirely reactive: two rounds of fixes to template customization and rerendering, then a documentation release moving the project's authoring guidelines onto the package website as living articles. Nothing in the window adds capability.

◆ Where it's heading

The releases are paced by training events rather than a roadmap. The 2.0.0 rerender bugs — blank author sections, parameters not propagating into both the YAML and the params chunk, custom sections mislabelled — are the kind found by people actually filling in a template, and the follow-up hotfix names a workshop explicitly as where the problems surfaced. Moving the guidelines into versioned site articles, revised after workshop feedback, continues that: the standard is being treated as part of the software rather than a document beside it.

◆ Prediction

With a workshop series named as upcoming in the entries, the next release is most likely another round of template fixes reported from a live session rather than new report types.

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.
