| panel.levelplot {lattice} | R Documentation |
This is the default panel function for levelplot.
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(...)
x, y, z |
variables defining the plot |
subscripts |
integer vector indicating what subset of x, y and
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 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). |
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. In the unusual case when col.regions is
not longer than at, it is repeated to be as long as
necessary.
|
alpha.regions |
numeric scalar controlling transparency of facets |
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.
