setEdgeLabelOpacityDirect: setEdgeLabelOpacityDirect

In tmuetze/Bioconductor_RCy3_the_new_RCytoscape: Display and manipulate graphs in Cytoscape >= 3.3.0

Description

In the specified CytoscapeWindow, set the opacity of the specified edge or edges. Low numbers, near zero, are transparent. High numbers, near 255, are maximally opaque: they are fully visible.

Usage

setEdgeLabelOpacityDirect(obj, edge.names, new.value)

Arguments

obj	a CytoscapeWindowClass object.
edge.names	one or more String objects, cy2-style edge names.
new.value	a numeric object, ranging from 0 to 255.

Value

None.

  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)
