plot-QuantileSD

R Documentation

Plot the values of the `QuantileSD`.

Description

Creates a K x K plot depicting a 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 parts (above the diagonal; i. e., \tau_1 > \tau_2) of

the quantile spectral density (red line),
the means of the quantile periodograms used in the simulation (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 'QuantileSD,ANY'
plot(
  x,
  ratio = 3/2,
  widthlab = lcm(1),
  xlab = expression(omega/2 * pi),
  ylab = NULL,
  frequencies = 2 * pi * (1:(floor(x@N/2)))/x@N,
  levels = getLevels(x, 1)
)

Arguments

`x`	The `QuantileSD` 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.
