setEdgeAttributesDirectR Documentation



Transfer the named edge attribute to Cytoscape. This method is required, for instance, if you wish to run a 'movie.' For example, if you have a timecourse experiment, with different values at successive time points of the 'phosphorylates' or 'binds' relationship between two nodes. With an edgeColor rule already specified, you can animate the display of the edges in the graph by pumping new values of the edge attributes, and then asking for a redraw. An example of such edge-attribute-driven animation can be found here....[todo].


setEdgeAttributesDirect(obj,, attribute.type, edge.names, values)


obj a CytoscapeWindowClass object. a string one of the attributes defined on the edges.
attribute.type a string from one of these three groups: (floating, numeric, double), (integer, int), (string, char, character). This parameter is required because RCytoscape cannot always infer the type of an attribute.
edge.names a list of strings, edge names
values a list of objects of the type specified by '', one per edge
