Cluster

Color nodes by cluster.

sg_cluster(sg, colors = c("#B1E2A3", "#98D3A5", "#328983", "#1C5C70",
  "#24C96B"), directed = TRUE, algo = igraph::cluster_walktrap,
  quiet = !interactive(), save_igraph = TRUE, ...)

sg_get_cluster(nodes, edges, colors = c("#B1E2A3", "#98D3A5", "#328983",
  "#1C5C70", "#24C96B"), directed = TRUE,
  algo = igraph::cluster_walktrap, quiet = !interactive(),
  save_igraph = TRUE, ...)

Arguments

sg

An object of class sigmajsas intatiated by sigmajs.
colors

Palette to color the nodes.
directed

Whether or not to create a directed graph, passed to graph_from_data_frame.
algo

An igraph clustering function.
quiet

Set to TRUE to print the number of clusters to the console.
save_igraph

Whether to save the igraph object used internally.
...

Any parameter to pass to algo.
nodes, edges

Nodes and edges as prepared for sigmajs.

Value

sg_get_cluster returns nodes with color variable.

Details

The package uses igraph internally for a lot of computations the save_igraph allows saving the object to speed up subsequent computations.

Functions

  • sg_cluster Color nodes by cluster.

  • sg_get_cluster helper to get graph's nodes color by cluster.

Examples

nodes <- sg_make_nodes()
edges <- sg_make_edges(nodes, 15)
#> Warning: Argument `n` is deprecated

sigmajs() %>%
  sg_nodes(nodes, id, size) %>%
  sg_edges(edges, id, source, target) %>%
  sg_layout() %>%
  sg_cluster()

clustered <- sg_get_cluster(nodes, edges)
