Plot Orders of Integration

Plots a vector with orders of integration of time series.

Usage

plot_order_integration(orders, show_names = TRUE, show_legend = TRUE,
  names_size = NULL, legend_size = NULL, cols = NULL)

orders: A "bootUR", "order_integration" object obtained from the function order_integration, or a vector with found orders of integration.
show_names: Show the time series' names on the plot (TRUE) or not (FALSE). Default is TRUE.
show_legend: Logical indicator whether a legend should be displayed. Default is TRUE.
names_size: Size of the time series' names if show_names = TRUE. Default takes ggplot2 defaults.
legend_size: Size of the text in the legend if show_legend = TRUE. Default takes ggplot2 defaults.
cols: Vector with colours for displaying the orders of integration. At least as many colours as orders of integration need to be supplied. Default supplies 4 colours for displaying up to \(I(3)\) series.

A ggplot2 object containing the plot of the orders of integration.

This function requires the package ggplot2 to be installed. If the package is not found, plotting is aborted.
