RCy3 (version 1.2.0)

initEdgeAttribute: initEdgeAttribute

Description

Create the edge attribute slot that the Bioconductor graph class requires, including a default value, and then specifying what the base type (or 'class') is -- 'char', 'integer', or 'numeric' -- which is needed by RCy3. This method converts these standard R data type names, to the forms needed by Cytoscape.

Usage

initEdgeAttribute(graph, attribute.name, attribute.type, default.value)

Arguments

graph

a Bioconductor graph object.

attribute.name

a string, the name of the new edge attribute.

attribute.type

a string, either 'char', 'integer', or 'numeric'

default.value

something sensible, of the right type

Value

Returns the modified graph.

Examples

  # first, delete existing windows to save memory:
  deleteAllWindows(CytoscapeConnection())

  g = new ('graphNEL', edgemode='directed')
  g = initEdgeAttribute (g, 'edgeType', 'char', 'associates with')
