plot-IntegrQuantileSD: Plot the values of the `IntegrQuantileSD`.

Description

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., \(\tau_1 \leq \tau_2\)) or the imaginary part (above the diagonal; i. e., \(\tau_1 > \tau_2\)) of

the integrated quantile spectral density (black line),

for the combination of levels \(\tau_1\) and \(\tau_2\) denoted on the left and bottom margin of the plot are displayed.

Usage

# S4 method for IntegrQuantileSD,ANY
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)),
  levels = getLevels(x, 1)
)

Value

Plots the simulated integrated quantile spectral density for all

frequencies and levels specified.

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.
