Network / force-directed graph layer — mark

Creates a network visualization with nodes and edges. Requires the ggraph and igraph packages.

Usage

mark_network(
  plot,
  layout = c("auto", "circle", "linear", "bipartite", "manual"),
  edge_colour = "grey70",
  edge_width = 0.5,
  node_colour = "#4E79A7",
  node_size = 5,
  ...
)

Arguments

plot: A plotit object. The data should be an igraph object.
layout: Layout algorithm: "auto" (default, uses layout_with_fr), "circle", "linear", "bipartite", or "manual".
edge_colour: Colour for edges (default "grey70").
edge_width: Width for edges (default 0.5).
node_colour: Fill colour for nodes (default "#4E79A7").
node_size: Size for nodes (default 5).
...: Other arguments passed to ggraph::geom_edge_link and ggraph::geom_node_point

Value

Modified plotit object
