\title{ Default Panel Function for dotplot}
\description{
  Default panel function for \code{dotplot}.
}
\usage{
panel.dotplot(x, y, horizontal = TRUE,
              pch, col, lty, lwd, 
              col.line, levels.fos,
              groups = NULL,
              \dots)
}
\arguments{
  \item{x,y}{ variables to be plotted in the panel. Typically y is the
    \sQuote{factor} }
  \item{horizontal}{ logical. If FALSE, the plot is \sQuote{transposed}
    in the sense that the behaviours of x and y are switched. x is now
    the \sQuote{factor}.  Interpretation of other arguments change
    accordingly. See documentation of \code{\link{bwplot}} for a fuller
    explanation.
  }
  \item{pch, col, lty, lwd, col.line}{ graphical parameters}
  \item{levels.fos}{ locations where reference lines will be drawn }
  \item{groups}{ grouping variable (affects graphical parameters)}
  \item{\dots}{
    extra parameters, passed to \code{panel.xyplot} which is responsible
    for drawing the foreground points (\code{panel.dotplot} only draws
    the background reference lines).
  }
}
\details{
  Creates (possibly grouped) Dotplot of \code{x} against \code{y} or
  vice versa
