TreeGraph function

TreeGraph

A function to produce the data structure needed to plot Event and Staged trees using RGraphviz.

TreeGraph(tree, solution = list(), name = c(), range.color = 1)

Arguments

• tree: Event.tree S4 object

• solution: list with two components:

  • numeric - score associated with a level
  • list of vectors - stage structure

• name: vector of strings - variable names

• range.color: (numeric) - it chooses the palette. If 1, it is used a 8-color palette. If 2, it is used a 501-color palette.

Returns

list:

• $node - node attributes

  • $node$nodes (vector) - set of situations.
  • node$label (vector) - it identifies the variable asscoiated with each position.
  • node$color (vector) - color of each situation. All situations coincident with a stage are depicted in black.

• $edge - edge attributes

  • $edge$edges (list) - set of list that emanates from each situation.
  • edge$label (vector) - edge labels.
