getAllNodeAttributes: getAllNodeAttributes

Description

Create a data frame with all the node attributes for the graph contained by the supplied CytoscapeWindow object. Only the local copy of the graph is queried. If you want all the (possibly different) node attributes from the Cytoscape network which corresponds to this graph, one option is to create a new CytoscapeWindow; see the existing.CytoscapeWindow function.

Usage

getAllNodeAttributes(obj, onlySelectedNodes=FALSE)

Arguments

obj

a CytoscapeWindowClass object object.

onlySelectedNodes

a logical variable, used to restrict the query.

Value

A data frame, with a column for each attribute, a row for each node.

Examples

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

  window.name <- 'demo.getAllNodeAttributes'
  cw <- CytoscapeWindow (window.name, graph=makeSimpleGraph ())
  displayGraph (cw)
  redraw (cw)
  layoutNetwork (cw, 'force-directed')
    # get all attributes for all nodes
  tbl.noa <- getAllNodeAttributes (cw, onlySelectedNodes=FALSE)
  tbl.noa
  #                   type lfc  label count
  # A               kinase  -3 Gene A     2

  # C         glycoprotein   3 Gene C   100
