B_G: Calculate B:G photon ratio from spectral irradiance.

In photobiologyPlants: Plant Photobiology Related Functions and Data

Description

This function returns the blue:green photon ratio of a light source spectrum.

Usage

B_G(spct, std = "Sellaro", use.cached.mult = FALSE,
  use.hinges = TRUE)

Arguments

spct	an object of class "source.spct"
std	select which definition of blue and green should be used, defaults to "Sellaro"
use.cached.mult	logical indicating whether multiplier values should be cached between calls
use.hinges	logical indicating whether to use hinges to reduce interpolation errors

Value

a single numeric nondimensional value giving the B:G photon ratio, with name attribute set to the name of the wavebands, with "(q:q)" appended.

Examples

B_G(sun.spct)
