panel.levelplot: Default Panel Function for levelplot

Description

This is the default panel function for 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,
                ...,
                col.regions)

Arguments

x, y, z
variables defining the plot
zcol
color numbers for each x,y combination
subscripts
which points to draw
at
cut points
shrink
either a numeric vector of length 2, or a list with components x and y which are numeric vectors of length 2.
labels
contour labels
label.style
contour
logical
region
logical
col, lty, lwd
graphical parameters for contour lines
...
extra parameters
col.regions
colors indexed by zcol

Details

The same function is used for both levelplot and contourplot (which differ only in default values of some arguments). Most arguments are self-evident. label.style controls choice of how label positions are determined (this is not very sophisticated yet). The shrink argument allows the rectangles to be resized, proportional to the z-value. The specification can be made separately for widths and heights, in terms of a length 2 numeric vector, which gives the minimum and maximum proportion of shrinkage (corresponding to min and max of z).
