get.neighborhood

Obtain the Neighborhood of a Given Vertex

Description

get.neighborhood returns the IDs of all vertices belonging to the in, out, or combined neighborhoods of v within network x.

Usage

get.neighborhood(x, v, type = c("out", "in", "combined"),
  na.omit = TRUE)

Arguments

`x`	an object of class `network`
`v`	a vertex ID
`type`	the neighborhood to be computed
`na.omit`	logical; should missing edges be ignored when obtaining vertex neighborhoods?

Details

Note that the combined neighborhood is the union of the in and out neighborhoods – as such, no vertex will appear twice.

Value

A vector containing the vertex IDs for the chosen neighborhood.

#Create a network with three edges
m<-matrix(0,3,3)
m[1,2]<-1; m[2,3]<-1; m[3,1]<-1
g<-network(m)

#Examine the neighborhood of vertex 1
