cyto_vis: Send graph to Cytoscape via CyREST

In uc-bd2k/KEGGlincs: Visualize all edges within a KEGG pathway and overlay LINCS data [option]

Description

View the KEGG pathway in Cytoscape. With either the 'expanded edges' or 'stacked nodes' layout, users can visualize and interact with the graphs [strictly] as they are documented in the most recent KGML available from KEGG. This function is a modified version of the function send2cy(), which is part of the cyREST utility functions.

Usage

cyto_vis(graph_object, title = "Cytoscape Graph Window",
  edge_width_attribute = "summary_score", port.number = 1234)

Arguments

graph_object	An igraph object such as the one generated by the function get_graph_object
title	An optional title for the graph when it is in Cytoscape
edge_width_attribute	The attribute that will be used for edge width; if data is not added or the attribute is not part of the graphing information, the edge width will default to 1.
port.number	The port address for Cytoscape

Value

A dynamic map in Cytoscape automatically formatted for convenient viewing.

Examples

p53_KEGG_mappings <- expand_KEGG_mappings(p53_KGML, FALSE)

p53_graph_object <- get_graph_object(nodes, edges)
                                      
## Not run:
