CRAN release ‘RLumShiny’ v0.2.5

by RLum.Network (July 14, 2025)

---

A new version of 'RLumShiny', the graphical user interface to our core package 'Luminescence', is now available on CRAN. In this release we have added a few new apps:

• aliquotsize to either estimate the number of grains on an aliquot or to compute the packing density (based on calc_AliquotSize());

• finitemixture to fit a k-component mixture to a De distribution with differing known standard errors (based on calc_FiniteMixture());

• huntley2006 to calculate the expected sample specific fraction of saturation based on the model of Huntley (2006), using the approach as implemented in Kars et al. (2008) or Guralnik et al. (2015) (based on calc_Huntley2006());

• irsarRF to analyse IRSAR RF measurements on K-feldspar samples performed using the protocol according to Erfurt et al. (2003) and beyond (based on analyse_IRSAR.RF());

• lmcurve to determine weighted non-linear least-squares estimates of the component parameters of an LM-OSL curve (Bulur 1996) for a given number of components (based on fit_LMCurve()).

We have also brought a number of cosmetic and stability improvements to the already existing apps.

We have written a bit more about the RLumShiny 0.2.5 release and our future plans for RLumShiny on the REPLAY website.

Enjoy!
