wl_units: Wavelengths of Spectra* objects

In inspectr: Storing, manipulating and analysis spectroscopy and associated data in R.

Description

Retrieves the wavelengths units and the spectral resolution from Spectra* objects.

Usage

wl_units(object)
wl_units(object) <- value
res(x)

Arguments

object, x	an object inheriting from class Spectra, or a "numeric" vector for resolution
value	a character string

Value

A vector. res is giving NULL for irregularly spaced wavelengths (eg when there is parts of the spectra data have been removed).

Examples

# Loading example data
data(australia)
spectra(australia) <- sr_no ~ ... ~ 350:2500

# Print wavelength information
wl(australia)
range(wl(australia))
res(australia)

# Manipulate wavelength information
wl(australia) <- wl(australia) + 1000
wl(australia)
