Internal function used in spectrum.car only. Not called by user.
Plotting method for objects of class "spectrum.car".
plotSpecCar(x, add = FALSE, ci = 0.95, log = "dB", xlab = "frequency",
ylab = NULL, type = "l", main = NULL, sub = NULL,...)an object of class "spectrum.car".
logical. If TRUE, add to already existing plot.
Coverage probability for confidence interval. Plotting of
the confidence bar is omitted unless ci is strictly
positive.
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" unless
options(ts.S.compat = TRUE) has been set, when it is
"dB".
the x label of the plot.
the y label of the plot.
the type of plot to be drawn, defaults to lines.
overall title for the plot.
a sub title for the plot.
