plot_small_metrics: Plot Small Sample Metrics

Description

This function provides an easy way to illustrate the output of small_metrics(), using the ggplot2 package. A grid of line charts is created for each metric and sample size. Each estimator is plotted with a different color and linetype. The plot can be saved in pdf format.

Usage

plot_small_metrics(
  x,
  colors = NULL,
  title = NULL,
  save = FALSE,
  path = getwd(),
  name = "myplot.pdf",
  width = 15,
  height = 8
)

Value

The plot is returned invisibly in the form of a ggplot object.

Arguments
