\title{Panel Function to Add a LOESS Smooth}
\description{
A predefined panel function that can be used to add a LOESS smooth
based on the provided data.
}
\usage{
panel.loess(x, y, span = 2/3, degree = 1,
family = c("symmetric", "gaussian"),
evaluation = 50,
lwd, lty, col, col.line, type,
horizontal = FALSE,
\dots, identifier = "loess")
}
\arguments{
\item{x, y}{ Variables defining the data to be used. }
\item{lwd, lty, col, col.line}{ Graphical parameters for the added
line. \code{col.line} overrides \code{col}. }
\item{type}{ Ignored. The argument is present only to make sure that
an explicitly specified \code{type} argument (perhaps meant for
another function) does not affect the display. }
\item{span, degree, family, evaluation}{ Arguments to
\code{\link{loess.smooth}}, for which \code{panel.loess} is
essentially a wrapper.
}
\item{horizontal}{
A logical flag controlling which variable is to be treated as the
predictor (by default \code{x}) and which as the response (by
default \code{y}). If \code{TRUE}, the plot is \sQuote{transposed}
in the sense that \code{y} becomes the predictor and \code{x} the
response. (The name \sQuote{horizontal} may seem an odd choice for
this argument, and originates from similar usage in
\code{\link{bwplot}}).
}
\item{\dots}{ Extra arguments, passed on to
\code{\link{panel.lines}}.
}
\item{identifier}{
A character string that is prepended to the names of grobs
that are created by this panel function.
}
}
\value{
The object returned by \code{\link[stats:scatter.smooth]{loess.smooth}}.
