In visa: Vegetation Imaging Spectroscopy Analyzer

Description

Constructor as.spectra creates a Spectra object.

Constructor as.spectra.database creates a SpectraDatabase object.

Usage

as.spectra(
  spectra = matrix(0),
  wavelength = numeric(0),
  w.unit = "nm",
  data = data.frame(),
  ...
)

as.spectra.database(
  spectra = matrix(0),
  wavelength = numeric(0),
  w.unit = "nm",
  data = data.frame(),
  ...
)

Arguments

spectra	A matrix
wavelength	A numeric vector
w.unit	A character string
data	A data.frame
...	Other parameters

Slots
