plot-IntegrQuantileSD: Plot the values of the 'IntegrQuantileSD'.
In tobiaskley/quantspec: Quantile-Based Spectral Analysis of Time Series

Description Usage Arguments Value

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.

## 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))

`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.
