Plot Generic for Break Down Uncertainty Objects

Description

Plot Generic for Break Down Uncertainty Objects

Usage

## S3 method for class 'break_down_uncertainty'
plot(
  x,
  ...,
  vcolors = DALEX::colors_breakdown_drwhy(),
  show_boxplots = TRUE,
  max_features = 10,
  max_vars = NULL
)

Arguments

x	an explanation created with break_down_uncertainty
...	other parameters.
vcolors	If NA (default), DrWhy colors are used.
show_boxplots	logical if TRUE (default) boxplot will be plotted to show uncertanity of attributions
max_features	maximal number of features to be included in the plot. By default it's 10.
max_vars	alias for the max_features parameter.

Value

a ggplot2 object.
