plot.spec {stats} | R Documentation |
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.
## S3 method for class 'spec'

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 subtitle 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. |
