With the Walktrap community finding algorithm, obtain the group membership values for each of the nodes in the graph.
get_cmty_walktrap(graph, steps = 4)
graph | a graph object of

steps | the number of steps to take for each of the random walks. |
a data frame with group membership assignments for each of the nodes.
