Extract spectral data from spectra filesSource:
Finds and imports reflectance/transmittance/absorbance data from spectra files in a given location.
Folder in which files are located (defaults to current working directory).
File extension to be searched for, without the "." (defaults to
txt). You can also use a character vector to specify multiple file extensions.
A vector with two numbers determining the wavelength limits to be considered (defaults to
Character to be used to identify decimal plates (defaults to
Column delimiting characters to be considered in addition to the default (which are: tab, space, and ";")
Should subdirectories within the
wherefolder be included in the search? (defaults to
Should subdirectory path be included in the name of the spectra? (defaults to
Should the extension search be case insensitive? (defaults to
Boolean indicated whether spectral data should be interpolated and pruned at every nanometre. Note that this option can only work if all input data samples the same wavelengths. Defaults to
A data.frame, containing the wavelengths in the first column and individual imported spectral files in the subsequent columns.
You can customise the type of parallel processing used by this function with
future::plan() function. This works on all operating systems, as well
as high performance computing (HPC) environment. Similarly, you can customise
the way progress is shown with the
(progress bar, acoustic feedback, nothing, etc.)
