plot-IntegrQuantileSD {quantspec}

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 signature '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)
)

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.

Value

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