  column_from,
  column_to,
  color_from,
  color_to,
  values,
  padding = 2,
  alpha = 0.4,
  display_labels = TRUE,
  match_label_color = TRUE,
  label_fontface = "bold",
  label_size = 10
)

Arguments

column_from: vector of character labels, indicating the lefthand side
column_to: vector of character labels, indicating the righthand side
color_from: vector of color values, indicating colors for the lefthand side
color_to: vector of color values, indicating colors for the righthand side
values: vector of values, indicating the width of the ribbon
padding: constant used for displaying space between ribbons
alpha: numeric, transparancy of colors (0 = complete transparent, 1 = opaque)

match_label_color: boolean used to indicate labels in same color as nodes
label_fontface: string used for styling the font of labels
label_size: number indicating the font size of labels

Value

a ggplot with geom_ribbons
