Plot an object of class performance — plot.performance • flexFitR

Creates plots for an object of class performance

Usage

# S3 method for class 'performance'
plot(
  x,
  id = NULL,
  type = 1,
  rescale = FALSE,
  linewidth = 1,
  base_size = 12,
  return_table = FALSE,
  ...
)

Arguments

x

An object of class performance, typically the result of calling performance().

id

An optional group ID to filter the data for plotting, useful for avoiding overcrowded plots. This argument is not used when type = 2.

type

Numeric value (1-3) to specify the type of plot to generate. Default is 1.

type = 1: Radar plot by uid
type = 2: Radar plot averaging
type = 3: Bar plot by model-metric

rescale

Logical. If TRUE, metrics in type 3 plot are (0, 1) rescaled to improve interpretation. Higher values are better models. FALSE by default.

linewidth

Numeric value specifying size of line geoms.

base_size

Numeric value for the base font size in pts. Default is 12

return_table

Logical. If TRUE, table to generate the plot is returned. FALSE by default.

...

Additional graphical parameters for future extensions.

Value

A ggplot object representing the specified plot.
