Function to convert igraph graph to a list suitable for networkD3

Function to convert igraph graph to a list suitable for networkD3

Usage
igraph_to_networkD3(g, group, what = "both")
Arguments
g
an igraph class graph object
group
an object that contains node group values, for example, those created with igraph's membership function.
what
a character string specifying what to return. If what = 'links' or what = 'nodes' only the links or nodes are returned as data frames, respectively. If what = 'both' then both data frames will be return in a list.
Value

A list of link and node data frames or only the link or node data frames.

Examples
# Load igraph
library(igraph)

# Use igraph to make the graph and find membership
karate <- make_graph("Zachary")
wc <- cluster_walktrap(karate)
members <- membership(wc)

# Convert to object suitable for networkD3
karate_d3 <- igraph_to_networkD3(karate, group = members)

# Create force directed network plot
forceNetwork(Links = karate_d3$links, Nodes = karate_d3$nodes,
             Source = 'source', Target = 'target', NodeID = 'name',
             Group = 'group')
