PlotPotential: Plot Potential

In earlywarnings: Early Warning Signals for Critical Transitions in Time Series

Plot Potential

Description

Visualization of the potential function from the movpotential function.

Usage

PlotPotential(
  res,
  title = "",
  xlab.text,
  ylab.text,
  cutoff = 0.5,
  plot.contours = TRUE,
  binwidth = 0.2,
  bins = NULL
)

Arguments

res	output from movpotential function
title	title text
xlab.text	xlab text
ylab.text	ylab text
cutoff	parameter determining the upper limit of potential for visualizations
plot.contours	Plot contour lines.
binwidth	binwidth for contour plot
bins	bins for contour plot. Overrides binwidth if given

Value

ggplot2 potential plot

       res <- movpotential_ews(X, param);

		     cutoff = 0.5, 
		     plot.contours = TRUE, binwidth = 0.2)
