Plot risk factor effects from rating_table() results — autoplot.riskfactor • insurancerating

Create a ggplot visualisation of a riskfactor object produced by rating_table(). Estimates are plotted per risk factor, with optional exposure bars and, optionally, an additional univariate line.

When univariate_scale = "reference", the univariate line is scaled to the model reference group. The reference group is determined as the level with model coefficient equal to 1. If no level is exactly equal to 1, the level with coefficient closest to 1 is used.

Usage

# S3 method for class 'riskfactor'
autoplot(
  object,
  risk_factors = NULL,
  ncol = 1,
  labels = TRUE,
  dec.mark = ",",
  ylab = "Relativity",
  fill = NULL,
  color = NULL,
  linetype = FALSE,
  univariate = NULL,
  univariate_var = "risk_premium",
  univariate_name = "Univariate",
  univariate_color = NULL,
  univariate_scale = c("reference", "mean"),
  rotate_angle = NULL,
  custom_theme = NULL,
  remove_underscores = FALSE,
  ...
)

Arguments

object: A riskfactor object returned by rating_table().
risk_factors: Character vector specifying which risk factors to plot. Defaults to all risk factors.
ncol: Number of columns in the patchwork layout. Default is 1.
labels: Logical; if TRUE, show exposure values as labels on the bars. Default is TRUE.
dec.mark: Character; decimal separator, either "," (default) or ".".
ylab: Character; label for the y-axis. Default is "Relativity".
fill: Fill color for the exposure bars. If NULL, taken from the internal palette.
color: Optional override for model line colors. If NULL, colors are taken from the internal discrete palette.
linetype: Logical; if TRUE, use different line types for models. Default is FALSE.
univariate: Optional univariate object returned by factor_analysis(). If supplied, the selected univariate statistic is added as an extra line.
univariate_var: Character; statistic from univariate to plot. Default is "risk_premium".
univariate_name: Character; legend label for the univariate line. Default is "Univariate".
univariate_color: Optional override for the univariate line color. If NULL, the internal risk premium color is used.
univariate_scale: Character; scaling applied to the univariate line. One of "reference" (default) or "mean".
rotate_angle: Numeric value for angle of labels on the x-axis (degrees).
custom_theme: List with customised theme options.
remove_underscores: Logical; remove underscores from labels.
...: Additional arguments passed to ggplot2 layers.

Value

A ggplot/patchwork object.
