Plot chain ladder results as a triangle table — plot

Visualise a "CLFit" object as a triangle-style heatmap table.

The what argument controls which values are shown:

"pred": Predicted cells only.
"full": Observed and predicted full triangle.
"data": Original observed data from x$data.

The label_style argument controls cell labels (only meaningful when method = "mack"):

"value": Projected value only. Applied to all cells.
"cv": Coefficient of variation (%) for projected cells.
"se": Standard error for projected cells.
"ci": Confidence interval for projected cells.

Usage

# S3 method for class 'CLFit'
plot_triangle(
  x,
  what = c("pred", "full", "data"),
  label_style = c("value", "cv", "se", "ci"),
  conf_level = 0.95,
  amount_divisor = 1e+08,
  theme = c("view", "save", "shiny"),
  nrow = NULL,
  ncol = NULL,
  ...
)

Arguments

x: An object of class "CLFit".
what: One of "pred", "full", or "data".
label_style: One of "value" (default), "cv", "se", or "ci". The uncertainty styles require method = "mack".
conf_level: Confidence level used when label_style = "ci". Default is 0.95.
amount_divisor: Numeric scaling factor for amount variables. Default is 1.
theme: A string passed to .switch_theme().
nrow, ncol: Number of rows and columns for ggplot2::facet_wrap().
...: Additional arguments passed to .switch_theme().

Value

A ggplot object.
