showSpectrum: Show Visual Ligh Spectrum

In raim/platexpress: Inspection and Analysis of Microbial Growth and Gene Expression Data

Description

shows the color spectrum of visible light along wavelengths in nm. NOTE that this is not a fully correct spectrum, see wavelength2RGB for details.

Usage

showSpectrum(
  wavelengths = 380:780,
  alpha = 99,
  pch = 19,
  cex = 3,
  ylab = "approximate color",
  main = "use findWavelength(3)",
  xlab = "wavelength, nm",
  ...
)

Arguments

wavelengths	vector of wavelengths to be plotted
alpha	the alpha factor (opacity) for plot symbols, min=1, max=255
pch	the plot symbol type, see ?par("pch")
cex	the plot symbol size, see ?par("cex")
ylab	ylab, see ?plot
main	main, see ?plot
xlab	xlab, see ?plot
...	further arguments to plot

Details

Plots the color spectrum over the selected wavelengths in nm. The utility functions plotWavelength and findWavelength can be used to plot and interactively (click on plot) find wavelengths. The function wavelength2RGB can then be used to convert this wavelength to RGB colors.
