formula
formula of the form z ~ x * y | g_1 * g_2 * ...
data
data frame in which variables are evaluated.
aspect
vector of length 2, giving the relative aspects of the
y-size/x-size and z-size/x-size of the enclosing rectangle.
scales
describes scales. not used yet
distance
between 0 and 1, controls amount of perspective. No
connection with the physical concept of distance in this
implementation (not clear what S+ does). individual values don't give
the same results as S-Plus, but all instances should be achievab
par.box
graphical parameters for box, not implemented yet
perspective
logical, whether to plot a perspective view
R.mat
initial rotation matrix (homogeneous coordinates). Not
implemented.
screen
A list determining the rotations to applied to the data
before being plotted. The initial position starts with the view
somewhere in the positive z-axis, and the x and y axes in the usual
position. Each component of the list should be named on
zoom
factor by which to scale the picture.
