Description Usage Arguments Value Author(s) See Also Examples

Specify how data attributes – for the specified named attribute – are mapped to the source arrow type.

1	setEdgeSourceArrowRule(obj, edge.attribute.name, attribute.values, arrows, default='Arrow')

`obj`	a `CytoscapeWindowClass` object.
`edge.attribute.name`	the edge attribute whose values will, when this rule is applied, determine the sourceArrow of each edge.
`attribute.values`	A list of scalar, discrete values. For instance, interaction types: 'phosphorylates', 'ubiquinates', 'represses', 'activates'
`arrows`	One arrow type for each of the attribute.values
`default`	The arrow type to use when an explicit mapping is not provided.

None.
