In RCytoscape: Display and manipulate graphs in Cytoscape

Description Usage Arguments Value Author(s) See Also Examples

This method expands or contracts the relative size of the objects (the graph) displayed in the CytoscapeWindow. A value of 1.0 typically renders the graph with an ample margin. A call to fitContent produces a zoom level of about 1.5.
