BayLum vs bcmaps: 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 bcmaps?
BC's spatial data package finished its sf migration and went back to adding layers
bcmaps provides British Columbia spatial layers and boundary data to R users, pulling from the BC Data Catalogue. The disruptive work is behind it: version 2.0.0 removed sp and raster support outright, leaving sf as the only returned class, in response to the retirement of rgdal and rgeos. Since then releases have been additive and small - cded_terra() replacing the deprecated raster variant, utm_convert() for reconciling coordinates across UTM zones, and in 2.3.0 a census dissemination block layer plus a dependency bump that removes an indirect reliance on the soon-to-be-archived leaflet.extras.

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.

◆ Current state

◆ Where it's heading
The package has spent most of its recent history reducing what it depends on rather than growing. Layers moved from a companion data package to direct Data Catalogue downloads in 1.1.0, ending manual update cycles; the sp and raster removal followed a full release of deprecation warnings; the terra transition took the same staged path. The recent dependency bump for leaflet.extras is the same instinct applied early. Feature work now arrives one function or one layer at a time, at roughly one release a year.
◆ Prediction
Expect further individual layer additions on request, and a completion of the terra transition through removal of the deprecated cded_raster(), given the package's pattern of announcing removals a release ahead.
