setEdgeOpacityDirect: setEdgeOpacityDirect
In RCytoscape: Display and manipulate graphs in Cytoscape

Description Usage Arguments Value Author(s) See Also Examples

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.

1	setEdgeOpacityDirect(obj, edge.names, new.values)

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

None.
