Overlay Community Blobs on a Network Plot — overlay

Plots a network with splot and overlays smooth blob shapes that mark node communities.

Usage

overlay_communities(
  x,
  communities,
  blob_colors = NULL,
  blob_alpha = 0.25,
  blob_linewidth = 0.7,
  blob_line_alpha = 0.8,
  ...
)

x

A network object passed to splot: tna, matrix, igraph, or cograph_network.

communities

Community assignments in any of these formats:

the name of an igraph cluster_* algorithm (e.g., "walktrap", "louvain", "leiden", "edge_betweenness"), matched partially; directed networks are collapsed to undirected before detection;
a numeric or factor membership vector in node order (e.g., c(1, 1, 2, 2, 3)), or named by node;
a named list of character vectors of node names;
a cograph_communities, igraph communities or tna_communities object.

blob_colors

Character vector of fill colors for blobs. Recycled if shorter than the number of communities. Default NULL uses the built-in blob palette.

blob_alpha

Numeric. Fill transparency (0-1). Default 0.25.

blob_linewidth

Numeric. Border line width. Default 0.7.

blob_line_alpha

Numeric. Border line transparency (0-1). Default 0.8.

...

Additional arguments passed to splot.

Invisibly, the cograph_network object returned by splot. Called for the side effect of plotting.

comm <- cograph::communities(regulation_net, method = "walktrap")
overlay_communities(regulation_net, comm)
