Potential analysis

Potential analysis, used for instance in [Hirota et al. Science, 2011, 334, 232-235.]

# Create simulated example data
X <- c(rnorm(1000, mean = 0), rnorm(1000, mean = -2), 
               rnorm(1000, mean = 2))
param <- seq(0,5,length=3000) 

# Run potential analysis
res <- movpotential_ews(X, param)

# Visualize
p <- PlotPotential(res$res, title = '', 
               xlab.text = '', ylab.text = '', 
           cutoff = 0.5, plot.contours = TRUE, binwidth = 0.2)
print(p)
