Graph

Create a graph.

e_graph(e, layout = "force", name = NULL, rm_x = TRUE, rm_y = TRUE, ...)

e_graph_gl(e, layout = "force", name = NULL, rm_x = TRUE, rm_y = TRUE, ...)

e_graph_nodes(
  e,
  nodes,
  names,
  value,
  size,
  category,
  symbol = NULL,
  legend = TRUE
)

e_graph_edges(e, edges, source, target)

Arguments

e	An echarts4 object as returned by e_charts.
layout	Layout, one of force, none or circular.
name	Name of graph.
rm_x, rm_y	Whether to remove the x and y axis, defaults to TRUE.
...	Any other parameter.
nodes	Data.frame of nodes.
names	Names of nodes, unique.
value	values of nodes.
size	Size of nodes.
category	Group of nodes (i.e.: group membership).
symbol	Symbols of nodes.
legend	Whether to add serie to legend.
edges	Data.frame of edges.
source, target	Column names of source and target.
