setEdgeTargetArrowRuleR Documentation

specify the arrow types to be used at the end of an edge, at the 'target' node

Description

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

Usage

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

Arguments

obj a CytoscapeWindowClass object.
edge.attribute.name the edge attribute whose values will, when this rule is applied, determine the targetArrow 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.
