plot.spec
Plotting Spectral Densities
Description
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
## S3 method for class 'spec' 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 |
add | logical. If |
ci | coverage probability for confidence interval. Plotting of the confidence bar/limits is omitted unless |
log | If |
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 | For multivariate time series, the type of plot required. Only the first character is needed. |
ylim, ... | Graphical parameters. |
