Solving Ordinary Differential Equations to Understand Luminescence.
RLumModel 
The R package 'RLumModel' by Johannes Friedrich (University of Bayreuth, Germany), Sebastian Kreutzer (Geography & Earth Sciences, Aberystwyth University, United Kingdom) and Christoph Schmidt (University of Lausanne, Switzerland) provides a collection of various R functions modelling luminescence signals in quartz and Al2O3, based on energy-band models.
For an introduction and further details, visit the RLumModel homepage.
Installation
Install the package
To install the stable version from CRAN, simply run the following from an R console:
install.packages("RLumModel")
To install the latest development builds directly from GitHub, run
if(!require("devtools"))
install.packages("devtools")
devtools::install_github("R-Lum/RLumModel@master")
To install a developer build other than ‘master’, replace the term ‘master’ in the codeline by the name of the wanted developer build.
Requirements
Depending on your OS please download and install one of the following:
- Windows: Rtools (provided by CRAN)
- macOS: Xcode (provided by Apple)
- Linux: gcc often comes pre-installed in most distributions. Should gcc be not available, however, we kindly refer to the exhaustive collection of installation guides depending on the Linux distribution.
Using RLumModel
Simple Example
model <- "Bailey2001"
sequence <- list(
IRR = c(20, 10, 1),
TL = c(20, 500, 5))
model.output <- model_LuminescenceSignals(
model = model,
sequence = sequence,
verbose = FALSE
)
Note
The package comes without any guarantee!
Please further note that this version is a development version and may change day by day. For stable branches please visit the package on CRAN.

Funding
The development of RLumModel benefited from the support by various funding bodies:
The initial work by Johannes Friedrich, Sebastian Kreutzer and Christoph Schmidt was supported by the DFG (2015–2018, SCHM 3051/4-1, “Modelling quartz luminescence signal dynamics relevant for dating and dosimetry”, SCHM 3051/4-1)
The work of Sebastian Kreutzer as package author was supported by LabEx LaScArBx (ANR - n. ANR-10-LABX-52) between 2017 and 2019.
From 2020, Sebastian Kreutzer received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No 844457 (project: CREDit).
