read_RF2R: Import RF-files to R

In Luminescence: Comprehensive Luminescence Dating Data Analysis

Import RF-files to R

Description

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.

Usage

read_RF2R(file, verbose = TRUE, ...)

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

Details

The results of spatially resolved IR-RF data are summarised in so-called RF-files (Mittelstraß and Kreutzer, 2021). The output of the function can be passed to function analyse_IRSAR.RF.

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. The header may contain key = "value" pairs, which will be stored in the info slot; incomplete pairs are silently dropped.

Function version

0.1.4
