title: How to create a sensible Hilbert Spectrum plot with R (computing environment)
body: <p>I am using the <a href="http://cran.r-project.org/web/packages/EMD/EMD.pdf" rel="nofollow noreferrer">EMD</a> package for R. This package has a spectrogram function for displaying a Hilbert Spectrum (calculated with hilbertspec). The output however, is really vague and black-white.</p>
  
  <p>This function does not seem to have an option for outputting color images. How can I get the spectrum displayed clearly and if possible in color.</p>
