Description

Creates chord diagram from edgelist data.frame.

Usage

chord(
  df,
  source.column = "source",
  target.column = "target",
  value.column = "value",
  adjacency.matrix = NULL,
  labels = NULL,
  edge.color = c("path", "input", "output", "none"),
  color.scheme = c("Spectral", names(d3po::color.schemes)),
  width = NULL,
  height = NULL,
  viewer = c("internal", "external", "browser")
)

Arguments

df	data.frame containing edgelist data.
source.column	Name of column containing source nodes. Defaults to "source".
target.column	Name of column containing target nodes. Defaults to "target".
value.column	Name of column containing edge values. Defaults to "value".
adjacency.matrix	Adjancency matrix of edge weights, as an alternative to edge list.
labels	Node names corresponding to rows/columns of adjacency.matrix.
edge.color	Method of coloring edges. The value "path" will create a gradient between two nodes. Defaults to "path".
color.scheme	Color scheme to use in visualization. See color.schemes for more details.
width	Desired width for output widget.
height	Desired height for output widget.
viewer	"internal" to use the RStudio internal viewer pane for output; "external" to display in an external RStudio window; "browser" to display in an external browser.

Details

Utilizes a script similar to https://observablehq.com/@d3/chord-diagram adapted to work with r2d3.

Value

A d3 object as returned by r2d3.

Examples

labels = c("spam", "eggs", "foo", "bar")

df = data.frame(source = rep(labels, each = 4),
                target = rep(labels, times = 4),
                value = c(11975, 5871, 8916, 2868,
                          1951, 10048, 2060, 6171,
                          8010, 16145, 8090, 8045,
                          1013, 990, 940, 6907))
