RCy3 (version 1.2.0)

makeRandomGraph: makeRandomGraph

Description

Create a random undirected graphNEL, useful for testing.Two default edge attributes are added, for demonstration purposes.

Usage

makeRandomGraph(node.count=12, seed=123)

Arguments

node.count

the number of nodes you wish to see in the graph

seed

an integer which, when supplied, allows reproducibility

Value

Returns (by default) a 12-node, rather dense undirected graph, with some attributes on the nodes and edges.

Examples

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

  g = makeRandomGraph (node.count=12, seed=123)

  ## The function is currently defined as
  function (node.count = 12, seed = 123) 
  {
      set.seed(seed)
      node.names = as.character(1:node.count)
      g = randomGraph(node.names, M <- 1:2, p = 0.6)
      attr(edgeDataDefaults(g, attr = "weight"), "class") = "DOUBLE"
      edgeDataDefaults(g, "pmid") = "9988778899"
      attr(edgeDataDefaults(g, attr = "pmid"), "class") = "STRING"
      return(g)
  }
