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,
  ...,
  itemStyle = list(opacity = 1)
)

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

e_graph_edges(e, edges, source, target, value, size)

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.
itemStyle	This option is available for for GL and canvas graph but is only necessary for GL.
nodes	Data.frame of nodes.
names	Names of nodes, unique.
value	Values of nodes or edges.
size	Sizes of nodes or edges.
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.

Examples

value <- rnorm(10, 10, 2)

nodes <- data.frame(
  name = sample(LETTERS, 10),
  value = value,
  size = value,
  symbol = sample(c("circle", "rect", "triangle"), 10, replace = TRUE),
  grp = rep(c("grp1", "grp2"), 5),
  stringsAsFactors = FALSE
)

value_edges <- sample(1:100, 20, replace = TRUE)
edges <- data.frame(
  source = sample(nodes$name, 20, replace = TRUE),
  target = sample(nodes$name, 20, replace = TRUE),
  value = value_edges,
  size = ceiling(value_edges/20),
  stringsAsFactors = FALSE
)
