Plot alpha decay parameter diagnostics

Visualize the spatial distribution and bracket variation of optimized alpha decay parameters.

Usage

plot_alpha(
  result,
  type = c("map", "histogram", "bracket"),
  summary_fn = "median",
  brackets = NULL,
  palette = "YlOrRd",
  breaks = "quantile",
  n_breaks = 5L,
  ...
)

Arguments

result

An interpElections_result object.

type

Character. Plot type: "map", "histogram", or "bracket".

summary_fn

Summary function for collapsing alpha across brackets when type = "map". One of "median" (default), "mean", "pop_weighted", "min", "max", "range", or an integer bracket index.

brackets

Integer vector. Bracket indices to include. NULL = all.

palette

Character. Color palette. Default: "YlOrRd".

breaks

Break method: "quantile", "continuous", "jenks", or numeric vector.

n_breaks

Integer. Number of breaks. Default: 5.

...

Ignored.

Value

A ggplot object (invisibly). Prints the plot.
