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.
