read_multi: Read spectral data from multiple files

In wincowgerDEV/OpenSpecy: Analyze, Process, Identify, and Share Raman and (FT)IR Spectra

Read spectral data from multiple files

Description

Wrapper functions for reading files in batch.

Usage

read_any(file, c_spec = T, c_spec_args = list(range = NULL, res = NULL), ...)

read_many(file, ...)

read_zip(file, ...)

Arguments

file	file to be read from or written to.
c_spec	logical, if multiple spectra should be concatenated or not. Multiple spectra will return a list if this is false.
c_spec_args	list of arguments passed to c_spec()
...	further arguments passed to the submethods.

Details

read_any() provides a single function to quickly read in any of the supported formats, it assumes that the file extension will tell it how to process the spectra. read_zip() provides functionality for reading in spectral map files with ENVI file format or as individual files in a zip folder. If individual files, spectra are concatenated. read_many() provides functionality for reading multiple files in a character vector and will return a list.

Value

All read_*() functions return OpenSpecy objects if a single spectrum or map is provided, otherwise they provide a list of OpenSpecy objects.
