Function reference
High-level functions
These functions offers an intuitive and user-friendly way to import (and possibly) transform multiple files at once in a given location. Please refer to the Batch import with lr_get_spec() and lr_get_metadata() vignette.
-
lr_get_spec() - Extract spectral data from spectra files
-
lr_get_metadata() - Extract metadata from spectra files
-
lr_convert_tocsv() - Convert spectral data files to csv files
Low-level parsers
These functions are destined to advanced users that want a more flexible way to import spectral data. They can only read a single file at a time and users are responsible for writing a loop if necessary. . Please refer to the Renormalise spectral data with a custom reference vignette.
