deleteNodeAttribute: deleteNodeAttribute

Description

Node and node attributes are usually added to a Cytoscape network by defining them on the graph used to construct a CytoscapeWindow. Once Cytoscape has been passed an attribute, however, it persists until you exit the application or delete it -- using the Cytoscape graphical user interface, or by calling this method.

Usage

deleteNodeAttribute(obj, attribute.name)

Arguments

obj

a CytoscapeConnectionClass object or CytoscapeWindow object.

attribute.name

a character string, the name of the attribute you wish to delete.

Value

nothing
