Handling wavelength and fwhm
Methods to access and set wavelength (band center) and full-width-half-max (fwhm) values for class Speclib.
## S4 method for signature 'Speclib' wavelength(object) ## S4 replacement method for signature 'Speclib,data.frame' wavelength(object) <- value ## S4 replacement method for signature 'Speclib,numeric' wavelength(object) <- value ## S4 method for signature 'Speclib' fwhm(object) ## S4 replacement method for signature 'Speclib,numeric' fwhm(object) <- value

Numeric vector or data.frame containing wavelength values. Must always be in nm! |
Wavelength (band center) and full-width-half-max (fwhm) values are given for each spectral band. The wavelength is mandatory for creation of Speclib and is used within the whole functionality of the package (e.g., noiseFiltering, spectralResampling, vegindex, nri, plot.Speclib, mask).
For wavelength<- and fwhm<-, the updated object. Otherwise a numeric vector of the wavelength and fwhm-values in nm is returned.
