This function imports .nir files generated by BUCHI NIRCal software.
Usage
read_nircal(file, response = TRUE, spectra = TRUE,
metadata = TRUE, progress = TRUE, verbose = TRUE)Arguments
- file
the name of the NIRCal (.nir) file which the data are to be read from. For URLs a temporary file is first downloaded and is then read.
- response
a logical indicating if the data of the response variables must be returned (default is
TRUE).- spectra
a logical indicating if the spectral data must be returned (default is
TRUE).- metadata
a logical indicating if the metadada must be returned (default is
TRUE).- progress
a logical indicating if a progress bar must be printed (default is
TRUE).- verbose
a logical indicating if the number of spectra and response variables (an also the ID's of the spectra without gain and/or temperature information) must be printed (default is
TRUE).
Value
a data.frame containing the metadata, response variables (if
response = TRUE) and spectra (if spectra = TRUE, embedded in the
data.frame as a matrix named ...$spc).
Details
The extension of the BUCHI NIRCal files is .nir. These files are used to store spectra generated by BUCHI N-500 and BUCHI NIRMaster FT-NIR sensors. See NIRCal technical data sheet.
