\title{ Useful Prepanel Function for Lattice}
\description{
These are predefined prepanel functions available in Lattice.
}
\usage{
prepanel.lmline(x, y, \dots)
prepanel.loess(x, y, span, degree, family, evaluation, \dots)
prepanel.qqmathline(x, y = x, distribution = qnorm,
p = c(0.25, 0.75), qtype = 7,
groups, subscripts,
\dots)
}
\arguments{
\item{x, y}{x and y values, numeric or factor}
\item{distribution}{ quantile function for theoretical
distribution. This is automatically passed in when this is used as a
prepanel function in \code{qqmath}.
}
\item{qtype}{ type of \code{\link{quantile}}}
\item{p}{
numeric vector of length two, representing probabilities. If used
with \code{aspect="xy"}, the aspect ratio will be chosen to make the
line passing through the corresponding quantile pairs as close to 45
degrees as possible.
}
\item{span, degree, family, evaluation}{ arguments controlling the
underlying \code{\link{loess}} smooth }
\item{groups, subscripts}{ See \code{\link{xyplot}}. Whenever
appropriate, calculations are done separately for each group and
then combined. }
\item{\dots}{ other arguments }
}
\value{
usually a list with components \code{xlim}, \code{ylim}, \code{dx} and
\code{dy}, the first two being used to calculate panel axes limits,
the last two for banking computations. The form of these components
are described under \code{\link{xyplot}}. There are also several
undocumented prepanel functions that serve as the default for high
level functions, e.g., \code{prepanel.default.xyplot}
