Import files produced by the IR-RF 'ImageJ' macro (SR-RF.ijm;
Mittelstraß and Kreutzer, 2021) into R and create a list of
RLum.Analysis objects
Arguments
- file
character (required): name of one or multiple RF files (URLs are supported); it can be the path to a directory, in which case the function tries to detect and import all RF files found in the directory.
- verbose
logical (with default): enable/disable output to the terminal.
- ...
not used, only for compatible reasons
Value
Returns an S4 RLum.Analysis object containing
RLum.Data.Curve objects for each curve. Results are
returned as a list when multiple files are processed or file is a list.
Details
The results of spatially resolved IR-RF data are summarised in so-called RF-files (Mittelstraß and Kreutzer, 2021). This functions provides an easy import to process the data seamlessly with the R package 'Luminescence'. The output of the function can be passed to function analyse_IRSAR.RF.
