Examples

  # first, delete existing windows to save memory:
  deleteAllWindows(CytoscapeConnection())

  cw <- CytoscapeWindow ('setEdgeColorRule.test', graph=makeSimpleGraph())
  displayGraph (cw)
  layoutNetwork (cw, 'force-directed')
  
  edgeType.values = c ('phosphorylates', 'synthetic lethal', 'undefined')
  colors = c ('#FF0000', '#FFFF00', '#00FF00')
  setEdgeColorRule (cw, 'edgeType', edgeType.values, colors, mode='lookup')

  score.values = c (-15, 0, 40);
  colors = c ('#00FF00', '#FFFFFF', '#FF0000')
  setEdgeColorRule (cw, 'score',  score.values, colors, mode='interpolate')
    # now swap the colors around
  colors = c ('#FF0000', '#FFFFFF', '#00FF00')
  setEdgeColorRule (cw, 'score',  score.values, colors, mode='interpolate')
