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 RCytoscape. This method converts these standard R data type names, to the forms needed by Cytoscape.

Usage

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

attribute.name

a string, the name of the new edge attribute.

attribute.type

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