\title{Plot lmList Confidence Intervals}
\usage{
\method{plot}{intervals.lmList}(x, \dots)
}
\alias{plot.intervals.lmList}
\arguments{
\item{x}{an object inheriting from class \code{intervals.lmList},
representing confidence intervals and estimates for the coefficients
in the \code{lm} components of the \code{lmList} object used to
produce \code{x}.
}
\item{\dots}{optional arguments passed to the Trellis \code{dotplot}
function.
}
}
\description{
A Trellis dot-plot of the confidence intervals on the linear model
coefficients is generated, with a different panel for each
coefficient. Rows in the dot-plot correspond to the names of the
\code{lm} components of the \code{lmList} object used to produce
\code{x}. The lower and upper confidence limits are connected by
a line segment and the estimated coefficients are marked with a
\code{"+"}. The Trellis function \code{dotplot} is used in this method
function.
}
\value{
a Trellis plot with the confidence intervals on the coefficients of
the individual \code{lm} components of the \code{lmList} that
generated \code{x}.
