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

  cw <- CytoscapeWindow ('setEdgeLabelOpacityDirect.test', graph=makeSimpleGraph())
  displayGraph (cw)
  layoutNetwork (cw, 'force-directed')
  edge.names = as.character (cy2.edge.names (cw@graph)) [1:2]
  setEdgeLabelDirect (cw, edge.names, 'some lable')
  # fade out
  for (i in 1:10) {
    setEdgeLabelOpacityDirect (cw, edge.names, 255 - (i * 25))
    }
  # fade in
  for (i in 1:10) {
    setEdgeLabelOpacityDirect (cw, edge.names, i * 25)
