\title{Useful panel function with qqmath}
\description{
Useful panel function with qqmath. Draws a line passing through the
points (usually) determined by the .25 and .75 quantiles of the sample
and the theoretical distribution.
}
\usage{
panel.qqmathline(x, y = x,
distribution = qnorm,
probs = c(0.25, 0.75),
qtype = 7,
groups = NULL,
\dots,
identifier = "qqmathline")
}
\arguments{
\item{x}{ The original sample, possibly reduced to a fewer number of
quantiles, as determined by the \code{f.value} argument to
\code{qqmath}
}
\item{y}{
an alias for \code{x} for backwards compatibility
}
\item{distribution}{
quantile function for reference theoretical distribution.
}
\item{probs}{
numeric vector of length two, representing probabilities.
Corresponding quantile pairs define the line drawn.
}
\item{qtype}{
the \code{type} of quantile computation used in
\code{\link{quantile}}
}
\item{groups}{
optional grouping variable. If non-null, a line will be drawn for
each group.
}
\item{\dots}{other arguments.}
\item{identifier}{
A character string that is prepended to the names of grobs
that are created by this panel function.
}
