This function plots the results of aspect_importance.

# S3 method for aspect_importance
plot(
  x,
  ...,
  bar_width = 10,
  show_features = aspects_on_axis,
  aspects_on_axis = TRUE,
  add_importance = FALSE,
  digits_to_round = 2,
  text_size = 3
)

Arguments

x	object of aspect_importance class
...	other parameters
bar_width	bar width
show_features	if TRUE, labels on axis Y show aspect names, otherwise they show features names
aspects_on_axis	alias for `show_features` held for backwards compatibility
add_importance	if TRUE, plot is annotated with values of aspects importance
digits_to_round	integer indicating the number of decimal places used for rounding values of aspects importance shown on the plot
text_size	size of labels annotating values of aspects importance, if applicable

Value

a ggplot2 object
