Plot the relative contributions of each of the base models in the ensemble model — plot_model_contributions.caret

The relative contributions are calculated using the caret::varImp function on the ensemble model. A scaling factor is applied to make the contributions sum to 100%.

Usage

# S3 method for class 'caret_stack'
plot_model_contributions(object, descending = TRUE, ...)

Arguments

object: A caret_stack object
descending: Whether to sort in descending order. If FALSE, the output is sorted in ascending order. Default is TRUE.
...: Not used. Included for S3 compatibility.

Value

A ggplot2 bar chart

Examples
