Visualize a multi-level network (using ggraph)

Source: R/visualize_mnet.R

Visualize a multi-level network, with the possibility of specifying separate layouts for each level. This is a somewhat hacky wrapper for arranging separate ggraph calls for each network level in a circle.

plot_mnet(
  net,
  lvl_attr = c("sesType"),
  layouts = rep("kk", n_levels),
  label = FALSE,
  directed = NULL,
  nodesize = 3,
  edgewidth = 0.5
)

Arguments

net

A tidygraph, igraph or statnet network object
lvl_attr

The name of the categorical node attribute specifying at which level a node is situated
layouts

A list of layouts (see ggraph::layout_ggraph) for every level e.g. for two levels list("auto","circle")
label

logical - should nodes be labelled? (defaults to false)
directed

whether the network object shall be interpreted as directed network. Per default, motifr::is.directed is used to determine that.
nodesize

The size of node displays, if displayed as points (if label = false)
edgewidth

The width of lines illustrating edges

Value

A ggraph object

Details

For more extensive visualization options, it is recommended to explore the layout_as_multilevel function included in the package graphlayouts.

Examples

plot_mnet(net = motifr::ml_net, lvl_attr = "sesType", layouts = list("kk", "circle"))
