Create a Spectra or SpectraLibrary

Description

Constructor as.spectra creates a Spectra object.

Constructor as.spectra.library creates a SpectraLibrary object.

Usage

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

as.spectra.library(
  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

spectra

A matrix

wavelength

A numeric vector

w.unit

A character string

data

A data.frame

Examples

s <- as.spectra(matrix(1:100, 4), 1:25, "nm", data.frame(x = letters[1:4]))
str(s)

s <- as.spectra.library(matrix(1:100, 4), 1:25, "nm", data.frame(x = letters[1:4]))
str(s)
