Question 1 part a, d, e, f, g, h

Construct and plot the network using the igraph package http://igraph.org/redirect.html and the adjacency list you wrote.

To assign vertex names you can write it as

g = graph(edges = c("a", "b", "b", "c"), directed = FALSE)

or

g = graph(edges = c(1, 2, 2, 3), directed = FALSE)

V(g)$name = c("a", "b", "c")

1. Answer the following questions about this graph. a. What is the degree distribution for th graph? b. What is the density of this graph? c. Draw the 1.5 egocentric network of node G. d. Which node(s) have the highest degree? What is the degree? e. Which node(s) have the lowest degree? What is the degree? f. Which node has the highest closeness centrality? g. Which node has the highest degree centrality? h. What is the centralization (based on degree) of the graph
