Autoplot for tariff segment objects

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
