panel.cloud

Arguments

x, y, z

numeric (or possibly factors) vectors representing the data to be displayed. The interpretation depends on the context. For panel.cloud these are essentially the same as the data passed to the high level plot (except if form

subscripts

index specifying which points to draw. The same x, y, z values (representing the whole data) are passed to panel.cloud for each panel. subscripts specifies the subset of rows to be used for the particular

groups

specification of a grouping variable, passed down from the high level functions.

perspective

logical, whether to plot a perspective view. Setting this to FALSE is equivalent to setting distance to 0

distance

numeric, between 0 and 1, controls amount of perspective. The distance of the viewing point from the origin (in the transformed coordinate system) is 1 / distance. This is described in a little more detail in the documentation for

screen

A list determining the sequence of rotations to be applied to the data before being plotted. The initial position starts with the viewing point along the positive z-axis, and the x and y axes in the usual position. Each component of the list s

R.mat

initial rotation matrix in homogeneous coordinates, to be applied to the data before screen rotates the view further.

par.box

graphical parameters for box, namely, col, lty and lwd. By default obtained from the parameter box.3d

xlim, ylim, zlim

limits for the respective axes. As with other lattice functions, these could each be a numeric 2-vector or a character vector indicating levels of a factor.

panel.3d.cloud, panel.3d.wireframe

functions that draw the data-driven part of the plot (as opposed to the bounding box and scales) in cloud and wireframe. This function is called after the `back' of the bounding box is drawn, but before the `front' is

aspect

aspect as in cloud

xlab, ylab, zlab

Labels, have to be lists. Typically the user will not manipulate these, but instead control this via arguments to cloud directly.

xlab.default

for internal use

ylab.default

for internal use

zlab.default

for internal use

scales.3d

list defining the scales

proportion

numeric scalar, gives the length of arrows as a proportion of the sides

scpos

A list with three components x, y and z (each a scalar integer), describing which of the 12 sides of the cube the scales should be drawn. The defaults should be OK. Valid values are x: 1, 3, 9, 11; y: 8, 5, 7, 6 and z: 4, 2, 10, 12. (See comme

wireframe

logical, indicating whether this is a wireframe plot

drape

logical, whether the facets will be colored by height, in a manner similar to levelplot. This is ignored if shade=TRUE.

at, col.regions, alpha.regions

deals with specification of colors when drape = TRUE in wireframe. at can be a numeric vector, col.regions a vector of colors, and alpha.regions

rot.mat

4x4 transformation matrix in homogeneous coordinates. This gives the rotation matrix combining the screen and R.mat arguments to panel.cloud

type

character vector, specifying type of cloud plot. Can include one or more of ``p'', ``l'', ``h'' or ``b''. ``p'' and ``l'' mean `points' and `lines' respectively, and ``b'' means `both'. ``h'' stands for `histogram', and causes a line to be dra

xlim.scaled, ylim.scaled, zlim.scaled

axis limits (after being scaled to the bounding box)

zero.scaled

z-axis location (after being scaled to the bounding box) of the X-Y plane in the original data scale, to which lines will be dropped (if within range) from each point when type = 'h'

cross

logical, defaults to TRUE if pch='+'. panel.3dscatter can represent each point by a 3d `cross' of sorts (it's much easier to understand looking at an example than from a description). This is different fr

shade

logical, indicating whether the surface is to be colored using an illumination model with a single light source

shade.colors.palette

a function (or the name of one) that is supposed to calculate the color of a facet when shading is being used. Three pieces of information is available to the function: first, the cosine of the angle between the incident light ray and the norm

light.source

a 3-vector representing (in cartesian coordinates) the light source. This is relative to the viewing point being (0, 0, 1/distance) (along the positive z-axis), keeping in mind that all observations are bounded within the [-0.5, 0.5] cube

polynum

quadrilateral faces are drawn in batches of polynum at a time. Drawing too few at a time increases the total number of calls to the underlying grid.polygon function, which affects speed. Trying to draw too many at onc

col.groups

colors for different groups

col, col.point, col.line, lty, lwd, cex, pch, alpha

graphical parameters

...

other parameters, passed down when appropriate
