getResponseType: Get the "response.type" attribute
Description
Function to read the "response.type" attribute of an existing response_spct
object.
Usage
getResponseType(x)
Arguments
x
a response_spct object
Value
character string
Details
Objects of class response_spct() can contain data for a response
spectrum or an action spectrum. Response spectra are measured using the
same photon (or energy) irradiance at each wavelength. Action spectra are
derived from dose response curves at each wavelength, and responsivity
at each wavelength is expressed as the reciprocal of the photon fluence
required to obtain a fixed level of response.
