ggDiagnose.tree: Diagnostic plot for 'tree' object ('ggplot2' based)

In benjaminleroy/ggDiagnose: Wrapper for Diagnostic Plots with ggplot2

Description

Utilizing work from Andie de Vries's function dendro_data.tree from the ggdendro package which is used in the dfCompile to create a list of data frames.

Usage

ggDiagnose.tree(x, type = c("proportional", "uniform"),
  split.labels = TRUE, leaf.labels = FALSE, text.size = 3, ...,
  show.plot = TRUE, return = FALSE)

Arguments

x	an object of class tree from the tree.
type	character string. If "uniform", the branches are of uniform length (only shows depth). Otherwise they are proportional to the decrease in impurity.
split.labels	if TRUE (the default), non-leaf nodes are labeled with splitting rule
leaf.labels	if TRUE, leaves are labeled with predicted value (the default is FALSE).
text.size	integer size for link[ggplot2]{geom_text} for labels.
...	extra attributes (currently not used)
show.plot	logic to display the graphics (group of graphics in this case)
return	logic to return list of graphics and the data frame to make the majority of graphics

Value

depending on show.plot and return it will return the visualization of the graphic and/or a list of both the list of data frames used the make the graphic and the individual graphic object.

Examples

library(tree)

tree.object <- tree(Species ~., data = iris)

plot(tree.object)

ggDiagnose.tree(tree.object, split.labels = FALSE)
