David,
Thansk again! Sarkar's Lattice book is excellent source for lattice.
Here is a link for all the figures and codes used in the book. You
example is figure 13.7.
http://lmdvr.r-forge.r-project.org/figures/figures.html
I got the first point! For the second point below, Figure 13.7 an
excellent example for projecting the 3D dataset onto the bounding
surface, but it's not what I meant. I think I didn't explain what I
wanted clearly. What I really wanted is a simple straight grid lines
across the tick marks for 3 bounding surfaces of the box, not a
projection of the 3D dataset. Hope I have explained clearly this time.
You have not convinced me that I misunderstood what you wanted. I
figured that you would use something other than transforming the data
driven contour lines. But if you want to use a lattice function there
is a panel.grid, but I still suspect it will need to be 3dto3d
transformed onto one of the "lim" extremes.
Many thanks
John

David,
That does the job! Thanks a lot.
Now I am very very close to what I want. Still have a
couple of
small adjustments to make.
1. I use drape=TRUE to draw grid and color on the
surface, is there
a parameter to adjust the density of the grid?
If you mean the spacing between points, then isn't that
determined by
the density of the gridded data arguments before they get
to the
wireframe function?
2. Is there a way that I can add grid to the axis
surface? I mean
the sides of the box, between x & y, between x
& z, and between y &
z? And I need to choose which 3 side of the box that I
want to add
grid?
See Figure 13.7 of Sarkar's Lattice text for an example of
a panel
function that collapses the contourLines of the volcano
dataset at the
top bounding surface by using ltransform3dto3d with a z
argument of
zlim.scaled[2]. I would think that a grid could be 3dto3d
transformed
similarly.

Thank you all for the help. It's fun to play with
wireframe

With the help document, i finally find a set
of values
of for x=,y=
and z= in "screen" argument that gives me the
correct
rotation of
the plot. But now it plots x and y axis (tick

and labels)
along the top of the plot. Is there one way to
plot x
and y axis on
the bottom of the plot?
Look at the scpos argument to specify the scales
location.
(Still
lacking an example and therrefore doing this from
memory.)

A search with the following
strategy:
RSiteSearch("lattice wireframe rotate
axes")
Followed by adding requests to search
earlier
years'
archives produced this link which has a
further
link to a
document that answers most of your
questions, at
least the
ones that are comprehensible:

Two z axes? How interesting!
My understanding is that the
screen=list(z=,y=,x=)
control the orientation of axes, but even
after
reading the
help page of screen argument, I still
don't
understand how
to use it.
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 should be named one
of "x",
"y" or "z"
(repititions are allowed), with their
values
indicating the
amount of rotation about that axis in
degrees."
Can anyone explain to me how the
screen
argument
works? And what values (x,y,z) I should
choose for
the
orientation that I want?
Another question is wireframe(0 will
draw all
8 edges
of the cubic by default, is there anyway
that I
can control
what edges I can draw, what I can hide?
thanks very much!
John
