Description

In the specified CytoscapeWindow, set the opacity of the source arrow of the specified edge or edges. Opacity is an integer between 0 (invisible) and 255 (fully rendered).

Usage

setEdgeSourceArrowOpacityDirect(obj, edge.names, new.values)

Arguments

obj

a CytoscapeWindowClass object.

edge.names

one or more cy2-style edge names, String objects.

new.values

one or more integer objects, between 0 and 255.

Value

Examples

  # WARNING: Method RCy3::setEdgeSourceArrowOpacityDirect() is not implemented in RCy3!

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

  cw <- CytoscapeWindow ('setEdgeSourceArrowOpacityDirect.test', graph=makeSimpleGraph())
  displayGraph (cw)
  layoutNetwork (cw, 'force-directed')

  edges.of.interest = as.character (cy2.edge.names (cw@graph))
    # make sure the source arrows are visible
  setEdgeSourceArrowShapeDirect (cw, edges.of.interest, 'Circle')

    # first try passing three edges and three arrow opacity values
  setEdgeSourceArrowOpacityDirect (cw, edges.of.interest, c (64, 128, 255))
  
    # now try passing three edges and one opacity value
  setEdgeSourceArrowOpacityDirect (cw, edges.of.interest, 32)

    # restore the default
  setEdgeSourceArrowOpacityDirect (cw, edges.of.interest, 255)
