\begin{Description}\relax
Plot profile likelihoods for \code{"mle"} objects.
\end{Description}
\begin{Usage}
\begin{verbatim}
## S4 method for signature 'profile.mle, missing':
plot(x, levels, conf = c(99, 95, 90, 80, 50)/100, nseg = 50,
     absVal = TRUE, ...)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{x}] an object of class \code{"profile.mle"} 
\item[\code{levels}] levels, on the scale of the absolute value of a t
statistic, at which to interpolate intervals.  Usually \code{conf}
is used instead of giving \code{levels} explicitly.
\item[\code{conf}] a numeric vector of confidence levels for profile-based
confidence intervals on the parameters.
\item[\code{nseg}] an integer value giving the number of segments to use in
the spline interpolation of the profile t curves.
\item[\code{absVal}] a logical value indicating whether or not the plots
should be on the scale of the absolute value of the profile t.
Defaults to \code{TRUE}.
\item[\code{...}] other arguments to the \code{plot} function can be passed here.
