\title{ Default Panel Function for levelplot }
\description{
This is the default panel function for \code{levelplot}.
}
\usage{
panel.levelplot(x, y, z, zcol,
subscripts,
at = mean(z),
shrink,
labels = NULL,
label.style = c("mixed", "flat", "align"),
contour = TRUE,
region = TRUE,
col = add.line$col,
lty = add.line$lty,
lwd = add.line$lwd,
cex = add.text$cex,
font = add.text$font,
fontfamily = add.text$fontfamily,
fontface = add.text$fontface,
col.text = add.text$col,
\dots,
col.regions)
panel.contourplot(\dots)
}
\arguments{
\item{x, y, z}{ variables defining the plot }
\item{zcol}{
color numbers for each x,y combination, used as indices for the
color vector \code{col.regions}
}
\item{subscripts}{ which points of \code{x,y,z} to draw }
\item{at}{ numeric vector specifying cut points }
\item{shrink}{
either a numeric vector of length 2 (meant to work as both x and y
components), or a list with components x and y which are numeric
vectors of length 2. This allows the rectangles to be scaled
proportional to the z-value. The specification can be made
separately for widths (x) and heights (y). The elements of the
length 2 numeric vector gives the minimum and maximum proportion of
shrinkage (corresponding to min and max of z).
}
\item{labels}{contour labels}
\item{label.style}{
controls choice of how label positions are determined.
}
\item{contour}{
logical, specifying whether contour lines should be
drawn
}
\item{region}{
logical, specifying whether inter-contour regions should be filled
with the appropriate color
}
\item{col, lty, lwd}{ graphical parameters for contour lines}
\item{cex, col.text, font, fontfamily, fontface}{ graphical parameters for contour labels}
\item{\dots}{ extra parameters }
\item{col.regions}{ colors indexed by zcol, used if \code{region=TRUE}
}
}
\details{
The same function is used for both \code{levelplot} and
\code{contourplot} (which differ only in default values of some
arguments). \code{panel.contourplot} is a simple wrapper to
\code{panel.levelplot}.
When \code{contour=TRUE}, the \code{contourLines} function is used to
calculate the contour lines.
