chord_plot {TOmicsVis}

Chord plot for visualizing the relationships of pathways and genes.

Description

Chord plot is used to visualize complex relationships between samples and genes, as well as between pathways and genes.

Usage

chord_plot(
  data,
  multi_colors = "VividColors",
  color_seed = 10,
  color_alpha = 0.3,
  link_visible = TRUE,
  link_dir = -1,
  link_type = "diffHeight",
  sector_scale = "Origin",
  width_circle = 3,
  dist_name = 3,
  label_dir = "Vertical",
  dist_label = 0.3,
  label_scale = 0.8
)
