Spectra

Constructor for the Spectra class.

Constructor for the Spectra class. Creates a Spectra object from scratch.

Spectra(wl = numeric(), nir = matrix(), id = as.character(NA), units = "nm")

`wl`	a numeric vector giving the wavelengths at with the spectra have been measured
`nir`	a `"matrix"` or a `"data.frame"` object giving the spectra values for each sample
`id`	a vector giving the unique id of each sample in the collection
`units`	a character giving the unit in which the wavelengths values are expressed

a new "Spectra" object

wls <- 350:2500
  id <- c("A", "B")
  nir <- matrix(runif(2*length(wls)), nrow = 2)
  s <- Spectra(wl = wls, nir = nir, id = id, units = "nm")
