\title{Compute and plot the multitaper spectrum estimate}
\description{
Plots the multitaper spectral estimate and the multitaper F-test.
}
\usage{
\method{plot}{mtm}(x, jackknife = FALSE, Ftest = FALSE, ftbase = 1.01, siglines = NULL, ...)
}
\arguments{
\item{x}{An object of the class mtm generated by spec.mtm.}
\item{jackknife}{Boolean variable indicating if jackknife
confidence intervals should be plotted, only applies if Ftest=FALSE.}
\item{Ftest}{Boolean variable indicating if the multitaper harmonic F-test
should be plotted instead of the spectrum.}
\item{ftbase}{Lowest value to be plotted when the F-test is
plotted. When Ftest = TRUE, max(ftestvalue, ftbase) is plotted.}
\item{siglines}{Vector of significance values (as probabilities, 0.0 to 1.0)
to plot as horizontal significance lines on the F-test plot. }
\item{...}{Arguments to be passed to methods, such as graphical
parameters (see 'par').}
}
\details{
The value log can be set to \dQuote{yes} (default), \dQuote{no}, or \dQuote{dB}
as in the function plot.spec.}
