Install the package under R environmemnt
type the command:
install.packages("igraph")
Starting with the package
don't forget to load the library:
library('igraph')
parse a network file in Pajek format and access to its memory representation through the variable 'g':
g <- read.graph(file='/your/path/.../file.net', format='pajek')
list vertex and their attributes of graph g:
V(g) # the list of all nodes
V(g)[0] # access the first node
list.vertex.attributes(g) # the list of all vertex attributes names
V(g)[0]$id # access the attribute 'id' for the first node
