In BayLum: Chronological Bayesian Models Integrating Optically Stimulated Luminescence and Radiocarbon Age Dating

BayLum 0.3.1 (2023-03-28)

This version of 'BayLum' requires R>=4.1.x!

Bugfixes and changes

• AgeS_Computation() & Age_OSLC14() had two instances of the MCMC-list. One has been removed. This essentially halves the amount of memory needed to store the output of these functions. (Thanks to G. Guérin for reporting) (#27)

• AgeS_Computation() crashed reproducibly, if the THETA matrix (as one possibility) was provided indeed as a file name instead of a matrix object; fixed (thanks to M. Heydari for reporting)

• AgeS_Computation() the function handles wrong user input for the Theta matrix more friendly by converting it automatically to a matrix if needed.

• create_ThetaMatrix() the function did not throw an error in all cases where sigma_s was obviously wrong; fixed (thanks to M. Heydari for reporting)

• Generate_DataFile_MG() the function now checks that the number of specified BIN/BINX-files matches the actual number of BIN/BINX-files present in the folders. If not, a warning is prompted. This prevents hard-to-track-down error messages and odd modelling results that erroneously encourage searching for problems with JAGS or the 'BayLum' models.

• plot_Ages() gained a couple of new arguments. First, plot_mode allows to switch between the standard plot output "ages" (the default) and the new option "density". The latter draws probability density curves instead of lines. Further arguments specific to the plot_mode = "density" are d_scale to scale the density plots in height and show_ages to show the Bayes estimator. More generally, legend.cex was added to enable a convenient scaling of the legend fonts; this works for both plot modes.

• plot_MCMC() gained additional support for BayLum.list returned by Age_OSLC14()

• plot_Scatterplots() The functions can now handle BayLum.list objects if returned by certain functions. Currently: AgesS_Computation(), Age_OSLC14()
