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., tau1<=tau2) or the imaginary parts (above the diagonal; i. e., tau1>tau2) of
the quantile spectral density (red line),
the means of the quantile periodograms used in the simulation (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 '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.
Returns
Plots the simulated quantile spectral density for all frequencies and levels specified.
Details
Currently, only the plot for the first component is shown.
