  5. Κατανομήέξω βαθμών plot(degree.distribution (jg, mode="out"), log="xy")

  6. scale-free networkBarabasi g <- barabasi.game(100, m=1) g <- simplify(g) ## simple plot igraph.par("plot.layout", layout.fruchterman.reingold) plot(g, vertex.size=3, vertex.label=NA, edge.arrow.size=0.6)

  7. Έξω-βαθμοίανά έτος deg.per.year <- tapply(degree(jg, mode="out"), V(jg)$year, mean) plot( names(deg.per.year), deg.per.year )

  8. Τυχαίο γράφημα (Erdos) g <- erdos.renyi.game(100, 1/100) V(g)$color <- sample( c("red", "black"), vcount(g), rep=TRUE) E(g)$color <- "grey" red <- V(g)[ color == "red" ] bl <- V(g)[ color == "black" ] E(g)[ red %--% red ]$color <- "red" E(g)[ bl %--% bl ]$color <- "black" plot(g, vertex.size=5, layout= layout.fruchterman.reingold)
