read_BIN2R: Import Risø BIN/BINX-files into R

In Luminescence: Comprehensive Luminescence Dating Data Analysis

Import Risø BIN/BINX-files into R

Description

Import a ⁠*.bin⁠ or a ⁠*.binx⁠ file produced by a Risø DA15 and DA20 TL/OSL reader into R.

Usage

read_BIN2R(
  file,
  show.raw.values = FALSE,
  position = NULL,
  n.records = NULL,
  zero_data.rm = TRUE,
  duplicated.rm = FALSE,
  fastForward = FALSE,
  show.record.number = FALSE,
  txtProgressBar = TRUE,
  forced.VersionNumber = NULL,
  ignore.RECTYPE = FALSE,
  pattern = NULL,
  verbose = TRUE,
  ...
)

Arguments

file	character or list (required): path and file name of the BIN/BINX file (URLs are supported). If input is a list it should comprise only characters representing each valid path and BIN/BINX-file names. Alternatively the input character can be just a directory (path), in this case the the function tries to detect and import all BIN/BINX files found in the directory.
show.raw.values	logical (with default): shows raw values from BIN-file for LTYPE, DTYPE and LIGHTSOURCE without translation in characters. Can be provided as list if file is a list.
position	numeric (optional): imports only the selected position. Note: the import performance will not benefit by any selection made here. Can be provided as list if file is a list.
n.records	numeric (optional): limits the number of imported records to the provided record id (e.g., n.records = 1:10 imports the first ten records, while n.records = 3 imports only record number 3. Can be used in combination with show.record.number for debugging purposes, e.g. corrupt BIN-files. Can be provided as list if file is a list.
zero_data.rm	logical (with default): remove erroneous data with no count values. As such data are usually not needed for the subsequent data analysis they will be removed by default. Can be provided as list if file is a list.
duplicated.rm	logical (with default): remove duplicated entries if TRUE. This may happen due to an erroneous produced BIN/BINX-file. This option compares only predecessor and successor. Can be provided as list if file is a list.
fastForward	logical (with default): if TRUE for a more efficient data processing only a list of RLum.Analysis objects is returned instead of a Risoe.BINfileData object. Can be provided as list if file is a list.
show.record.number	logical (with default): shows record number of the imported record, for debugging usage only. Can be provided as list if file is a list.
txtProgressBar	logical (with default): enables or disables txtProgressBar.
forced.VersionNumber	integer (optional): allows to cheat the version number check in the function by own values for cases where the BIN-file version is not supported. Can be provided as list if file is a list. Note: The usage is at own risk, only supported BIN-file versions have been tested.
ignore.RECTYPE	logical (with default): this argument allows to ignore values in the byte 'RECTYPE' (BIN-file version 08), in case there are not documented or faulty set. In this case the corrupted records are skipped.
pattern	character (optional): argument that is used if only a path is provided. The argument will than be passed to the function list.files used internally to construct a list of wanted files
verbose	logical (with default): enables or disables verbose mode
...	further arguments that will be passed to the function Risoe.BINfileData2RLum.Analysis. Please note that any matching argument automatically sets fastForward = TRUE

Details

The binary data file is parsed byte by byte following the data structure published in the Appendices of the Analyst manual p. 42.

For the general BIN/BINX-file structure, the reader is referred to the Risø website: https://www.fysik.dtu.dk

Value

Returns an S4 Risoe.BINfileData object containing two slots:

METADATA	A data.frame containing all variables stored in the BIN-file.
DATA	A list containing a numeric vector of the measured data. The ID corresponds to the record ID in METADATA.

If fastForward = TRUE a list of RLum.Analysis object is returned. The internal coercing is done using the function Risoe.BINfileData2RLum.Analysis
