plot-IntegrQuantileSD function

Plot the values of the IntegrQuantileSD.

Creates a K x K plot depicting an integrated quantile spectral density. In each of the subplots either the real part (on and below the diagonal; i. e., $tau1 <= tau2$) or the imaginary part (above the diagonal; i. e., $tau1 > tau2$) of

• the integrated quantile spectral density (black line),

for the combination of levels $tau1$ and $tau2$

denoted on the left and bottom margin of the plot are displayed.

plot(
  x,
  ratio = 3/2,
  widthlab = lcm(1),
  xlab = expression(omega/2 * pi),
  ylab = NULL,
  frequencies = 2 * pi * (1:(floor(getN(getQuantileSD(x))/2)))/getN(getQuantileSD(x)),

)

Arguments

• x: The IntegrQuantileSD to plot
• ratio: quotient of width over height of the subplots; use this parameter to produce landscape or portrait shaped plots.
• widthlab: width for the labels (left and bottom); default is lcm(1), cf. layout.
• xlab: label that will be shown on the bottom of the plots; can be an expression (for formulas), characters or NULL to force omission (to save space).
• ylab: label that will be shown on the left side of the plots; can be an expression (for formulas), characters or NULL to force omission (to save space).
• frequencies: a set of frequencies for which the values are to be plotted.
• levels: a set of levels for which the values are to be plotted.

Returns

Plots the simulated integrated quantile spectral density for all frequencies and levels specified.
