plot_tree: Plot Decision Tree Function

In DARTH-git/Dectree: Decision Tree Constructor

Description

This function creates a plot of the decision tree with customizable appearance.

Usage

plot_tree(tree, edge.label.display = "both",
  vertex.label.display = "end", edge.label.position = 0.33,
  vertex.size = 7, font.size = 3, plot.padding = "auto",
  color.root = "yellow", color.internal = "green", color.end = "red",
  theme = FALSE)

Arguments

tree	a decision tree/tree object generated by create_tree()
edge.label.display	edge label mode, options: - "all","both": concatenate edge names and probabilities (default) - "label": show edge names only - "probability": show edge probabilities only - "none": don't show edge labels
vertex.label.display	vertex label mode, options: - "all": show labels for all vertices - "end": show labels only for end vertices (default) - "none": don't show vertex labels
edge.label.position	how far along the edge's straight part to display the label ([0-1], default = 0.33)
vertex.size	size of vertices in mm (default = 7)
font.size	font size in edge and vertex labels (default = 3)
plot.padding	left and right padding to add to the plot, options: - "auto": automatically set based on font size and max label length (default) - c(left, right): manually set based on provided vector
color.root	color of the root node (default = "yellow")
color.internal	color of internal, i.e. not root or end nodes (default = "green")
color.end	color of the end nodes (default = "red")
theme	theme to apply to the final plot (default = empty) refer to https://ggplot2.tidyverse.org/reference/theme.html for more on ggplot2 themes

Examples

tree <- plot_tree(read.csv("branches.csv"))
