setEdgeSourceArrowColorRule: Specify Rule for the Source Arrow Color
In RCytoscape: Display and manipulate graphs in Cytoscape

Description Usage Arguments Value Author(s) See Also Examples

Specify how edge attributes – that is, data values of the specified edge attribute – control the color of the source arrow, found at the end of an edge, where it connects to the source node.

1	setEdgeSourceArrowColorRule(obj, edge.attribute.name, attribute.values, colors, default.color='#000000')

`obj`	a `CytoscapeWindowClass` object.
`edge.attribute.name`	the edge attribute whose values will, when this ColorRule is applied, determine the color of the source arrow for each edge.
`attribute.values`	A list of scalar, discrete values. For instance, interaction types: 'phosphorylates', 'ubiquinates', 'represses', 'activates'
`colors`	A color for each of the attribute.values
`default.color`	The color to use when an explicit mapping is not provided. (Note: this is broken in Cytoscape 2.7)

None.
