panel.levelplot: Default Panel Function for levelplot

Description

This is the default panel function for levelplot.

Usage

panel.levelplot(x, y, z, 
                subscripts,
                at = pretty(z),
                shrink,
                labels = NULL,
                label.style = c("mixed", "flat", "align"),
                contour = FALSE,
                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,
                ...,
                col.regions = regions$col,
                alpha.regions = regions$alpha)
panel.contourplot(...)

Arguments

x, y, z

variables defining the plot

subscripts

which points of x,y,z to draw

at

numeric vector specifying breakpoints for change in colors

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 ca

labels

contour labels

label.style

controls choice of how label positions are determined.

contour

logical, specifying whether contour lines should be drawn

region

logical, specifying whether inter-contour regions should be filled with the appropriate color

col, lty, lwd

graphical parameters for contour lines

cex, col.text, font, fontfamily, fontface

graphical parameters for contour labels

...

extra parameters

col.regions

a vector of colors used if region=TRUE. Usually a subset of the colors are used, the exact number being one more than the length of at. These are chosen to be roughly equally spaced along col.regions.

alpha.regions

numeric scalar controlling transparency of facets

Details

The same function is used for both levelplot and contourplot (which differ only in default values of some arguments). panel.contourplot is a simple wrapper to panel.levelplot.

When contour=TRUE, the contourLines function is used to calculate the contour lines.
