Add a sequence arc layer — geom

Draws arcs (or straight lines, depending on the curvature setting) representing sequences in the chord diagram. Sequence layout parameters (order, orientation, radius, curvature, colors, etc.) are specified here.

Usage

geom_seq(
  mapping = NULL,
  data = NULL,
  seq_order = NULL,
  seq_labels = NULL,
  seq_orientation = NULL,
  seq_gap = NULL,
  seq_radius = NULL,
  seq_curvature = NULL,
  seq_colors = NULL,
  linewidth = 0.9,
  show_legend = TRUE,
  legend_position = "right",
  ...
)

Arguments

mapping: Default NULL (uses pre-computed data)
data: Default NULL (retrieved automatically from the layout)
seq_order: Optional character vector. Specifies the drawing order of sequences
seq_labels: Optional character vector or named vector. Sequence labels
seq_orientation: Optional numeric (1 or -1). Sequence orientation, default 1
seq_gap: Optional numeric. Gap proportion between sequences, default 0.03
seq_radius: Optional numeric (> 0). Sequence arc radius, default 1.0
seq_curvature: Optional numeric. Arc curvature (0=straight, 1=standard arc, >1=more curved), default 1.0
seq_colors: Optional color vector or named vector. Sequence colors
linewidth: Arc line width, default 0.9
show_legend: Whether to show the legend for this layer, default TRUE
legend_position: Position of this layer's legend (the Seq ID legend): one of "left", "right", "top", "bottom" or "inside", default "right". Pass NULL to let the legend follow theme(legend.position = ...) together with the other legends. Can also be set with theme(legend.position.seq = ...).
...: Additional arguments passed to geom_path()

Value

A list of ggplot2 layers

Examples

library(ggchord)
data(seq_data_example)
p <- ggchord(seq_data_example) + geom_seq()
p
