cograph (version 2.7.2)

overlay_communities: Overlay Community Blobs on a Network Plot

Description

Render a network with splot and overlay smooth blob shapes highlighting node communities.

Usage

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

Value

The splot result — a cograph_network

object — invisibly. Called for the side effect of drawing.

Arguments

x

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

communities

Community assignments in any format: a method name (e.g., "walktrap", "louvain"), a numeric or factor membership vector (e.g., c(1, 1, 2, 2, 3)), a named list of character vectors, a cograph_communities object, or a 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.

Examples

set.seed(1)
mat <- matrix(runif(25), 5, 5,
              dimnames = list(LETTERS[1:5], LETTERS[1:5]))
diag(mat) <- 0
overlay_communities(mat, list(g1 = c("A","B"), g2 = c("C","D","E")))

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