addCyNode

Description

Given a CytoscapeWindow containing a (possibly empty) graph, this method adds a node. Node attributes are added separately, via successive calls to sendNodeAttributesDirect. The new node must be unique – not already a member of the graph as known to Cytoscape.

Usage

1
addCyNode(obj, nodeName)

Arguments

obj

a CytoscapeWindowClass object.

nodeName

a character string object.

Value

None.
