extraction: Subnetwork extraction

In ProNet: Biological Network Construction, Visualization and Analyses

Description

Extract a sub network from the original one.

Usage

extraction(graph, mode = c("exact", "sample"), sample.number = 10,
  nodes = NULL, vertex.name = NULL, vertex.expression = NULL, ...)

Arguments

graph	An igraph object.
mode	Extraction mode, either be exact or sample.
sample.number	Sampled nodes if mode is sample, no more than the total nodes in the network. Default value is 10.
nodes	A vector of vertex id to extract the subnetwork if mode is exact.
vertex.name	A vector of vertex name to extract the subnetwork if mode is exact.
vertex.expression	Attribute used to choose the vertex and extract the subnetwork.
...	Other vertex or edge atrributes.

Value

An igraph object.

Examples

g<-graph.ring(100)
g1<-extraction(g,mode="sample",sample.number=5)
