\title{Add Confidence limits bar to plot}
\usage{
confband(
  x,
  lower,
  upper,
  center = NULL,
  line = TRUE,
  delta = 0.07,
  centermark = 0.03,
  pch,
  blank = TRUE,
  vert = TRUE,
  polygon = FALSE,
  alpha = 1,
  step = FALSE,
  ...
)
}
\arguments{
\item{x}{Position (x-coordinate if vert=TRUE, y-coordinate otherwise)}

\item{lower}{Lower limit (if NULL no limits is added, and only the
center is drawn (if not NULL))}

\item{upper}{Upper limit}

\item{center}{Center point}

\item{line}{If FALSE do not add line between upper and lower bound}

\item{delta}{Length of limit bars}

\item{centermark}{Length of center bar}

\item{pch}{Center symbol (if missing a line is drawn)}

\item{blank}{If TRUE a white ball is plotted before the center is
added to the plot}

\item{vert}{If TRUE a vertical bar is plotted. Otherwise a horizontal
bar is used}

\item{polygon}{If TRUE polygons are added between 'lower' and 'upper'}

\item{alpha}{transparency of fill-color of polygon (alpha<1)}

\item{step}{Type of polygon (step-function or piecewise linear)}

\item{...}{Additional low level arguments (e.g. col, lwd, lty,...)}
}
