plot.spec
Plotting Spectral Densities
Plotting method for objects of class "spec". For multivariate
time series it plots the marginal spectra of the series or pairs plots
of the coherency and phase of the cross-spectra.
Usage
"plot"(x, add = FALSE, ci = 0.95, log = c("yes", "dB", "no"), xlab = "frequency", ylab = NULL, type = "l", ci.col = "blue", ci.lty = 3, main = NULL, sub = NULL, plot.type = c("marginal", "coherency", "phase"), ...)
plot.spec.phase(x, ci = 0.95, xlab = "frequency", ylab = "phase", ylim = c(-pi, pi), type = "l", main = NULL, ci.col = "blue", ci.lty = 3, ...)
plot.spec.coherency(x, ci = 0.95, xlab = "frequency", ylab = "squared coherency", ylim = c(0, 1), type = "l", main = NULL, ci.col = "blue", ci.lty = 3, ...)Arguments
- x
- an object of class
"spec". - add
- logical. If
TRUE, add to already existing plot. Only valid forplot.type = "marginal". - ci
- coverage probability for confidence interval. Plotting of
the confidence bar/limits is omitted unless
ciis strictly positive. - log
- If
"dB", plot on log10 (decibel) scale (as S-PLUS), otherwise use conventional log scale or linear scale. Logical values are also accepted. The default is"yes"unlessoptions(ts.S.compat = TRUE)has been set, when it is"dB". Only valid forplot.type = "marginal". - xlab
- the x label of the plot.
- ylab
- the y label of the plot. If missing a suitable label will be constructed.
- type
- the type of plot to be drawn, defaults to lines.
- ci.col
- colour for plotting confidence bar or confidence intervals for coherency and phase.
- ci.lty
- line type for confidence intervals for coherency and phase.
- main
- overall title for the plot. If missing, a suitable title is constructed.
- sub
- a sub title for the plot. Only used for
plot.type = "marginal". If missing, a description of the smoothing is used. - plot.type
- For multivariate time series, the type of plot required. Only the first character is needed.
- ylim, ...
- Graphical parameters.
