makeRandomGraph

Description

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

Usage

1
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.

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)
}
