Spectrolyzer fingerprint loader — Spectro_load_fingerprint • TUBAFsoilFunctions

NOTE: Removes flagged spectra. Generalised fingerprint load-in for spectrolyzer data.

Usage

Spectro_load_fingerprint(
  directory,
  wavelengths = seq(200, 750, 2.5),
  sel_wavelengths = seq(200, 722.5, 2.5),
  id = T
)

Arguments

directory: Path to unzipped fingerprint-folder.
wavelengths: Vector of wavelengths. Column names of measured wavelengths. default is 200-750 nm in 2.5 nm steps
sel_wavelengths: Vector of wavelengths. Range of wavelengths that shall be returned (<= range of wavelengths)
id: Boolean. Should serial No be added as column to the tibble (for ID-ing the spectrolyzer later). Default=T. For addition of id-column, the metadata-file must be present in directory

Value

A nested tibble with the columns Date_Time (POSIXct), spc with spc$sel_wavelengths (absorbances at wavelength) and, if id==TRUE, the Serial_No, containing the spectrolyzer id.
