Autoplot for bootstrap_performance objects — autoplot.bootstrap

autoplot() method for objects created by bootstrap_performance(). Produces a histogram and density plot of the bootstrapped RMSE values, with the RMSE of the original fitted model shown as a dashed vertical line. Optionally, 95% quantile bounds are shown as dotted vertical lines.

Usage

# S3 method for class 'bootstrap_performance'
autoplot(object, fill = "#E6E6E6", color = NA, ...)

Arguments

object: An object of class "bootstrap_performance", produced by bootstrap_performance().
fill: Fill color of the histogram bars. Default = "#E6E6E6".
color: Border color of the histogram bars. Default = NA, which removes bar borders.
...: Additional arguments passed to ggplot2::autoplot().
