Autoplot for tariff segment objects

Description

autoplot() method for objects created by derive_tariff_segments(). Produces a ggplot2::ggplot() of the fitted GAM together with the derived tariff segment boundaries. Optionally, confidence intervals and observed data points can be added.

Usage

## S3 method for class 'tariff_segments'
autoplot(
  object,
  confidence = FALSE,
  color_gam = "steelblue",
  show_observations = FALSE,
  color_splits = "grey50",
  size_points = 1,
  color_points = "black",
  rotate_labels = FALSE,
  remove_outliers = NULL,
  conf_int = NULL,
  ...
)

Arguments

object	An object of class "tariff_segments", produced by derive_tariff_segments().
confidence	Logical, whether to plot 95% confidence intervals. Default = FALSE.
color_gam	Color of the fitted GAM line. Default = "steelblue".
show_observations	Logical, whether to add observed data points for each level of the risk factor. Default = FALSE.
color_splits	Color of the vertical split lines. Default = "grey50".
size_points	Numeric, size of points if show_observations = TRUE. Default = 1.
color_points	Color of observed points. Default = "black".
rotate_labels	Logical, whether to rotate x-axis labels by 45 degrees. Default = FALSE.
remove_outliers	Numeric, exclude observations above this value from the plot (helps with extreme outliers). Default = NULL.
conf_int	Deprecated. Use confidence instead.
...	Additional arguments passed to ggplot2::autoplot().

Value

A ggplot2::ggplot object.
