add points to wireframe
Hello
R-classicist won't like the following question due to there's no minimal reproducible example and the question was posted already.
Anyway I'm not able understand this rather complicated version of "add points to wireframe".
what I have is matrix 3x2000 with a dem<-(x,y,z, coordinates) (not provided).
with follwing code I want to produce the wireframe and add some

lattice: wireframe "eats up" points; how to make points on wireframe visible?
Dear expeRts,
I would like to add two points to a wireframe plot. The points have (x,y,z) coordinates
where z is determined to be on the wireframe [same z-value]. Now something strange
happens. One point is perfectly plotted, the other isn't shown at all. It only
appears if I move it upwards in z-direction by adding a positive number. So somehow
it disappears in the wireframe-surface

Adding points to wireframe
Hi,
I am using function wireframe from package lattice to draw a 3D surface.
I would like to add a few points on the surface. I read in a post from
Deepayan Sarkar that "To do this in a wireframe plot you would probably
use the panel function panel.3dscatter". Does someone have an example?
When calling panel.3dscatter with only x, y and z arguments I get

Adding points to a wireframe: 'x and units must have length >0' error
Hi,
I'm trying to follow the suggestions given by Deepayan Sarkar in this
message:
http://tolstoy.newcastle.edu.au/R/help/05/11/16135.html
to plot 3-D points on a wireframe plot. The problem is that I keep getting a
partly formed plot- with the colored lattice visible but no axis labels or
additional points- with the error message "error using packet 1, 'x' and

wireframe - add data points
Hello all,
I’m trying to add some data points to a wireframe. X an Y axis are independent variables, Z axis is predicted probability. I’d like to add the original data points on which the predicted probabilities are based to the wireframe. I’ve followed some of the previous post on this but get stuck :

Adding points to a wireframe with conditioning variable
I would like to add points to a wireframe but with a conditioning variable. I
found a solution for this without a conditioning variable here,
http://finzi.psych.upenn.edu/R/Rhelp02a/archive/65321.html. Does anyone know
how to plot a wireframe conditioned on a variable and add the points
conditioned on the same variable, similar to the solution at the link above?

Add lines (contours) to lattice wireframe plot
Hi,
I draw a surface corresponding to bivariate density of independent
variables (rho=0) using persp(). Then I add a contour line (i.e.,
circle in my case) at a particular density. Below is a minimal example
of what I have so far.
# Bivariate density
dnorm2d <- function(x, y, rho = 0) {
xoy = (x^2 - 2 * rho * x * y + y^2)/(2 * (1 - rho^2))
density = exp(-xoy)/(2 * pi * sqrt(1 - rho^2))

coloring wireframe plot with independent/separate matrix of color values.
Dear R Users,
I am trying to plot a matrix (a Digital Elevation Model) using wireframe
[lattice] and color that matrix based on a separate/independent matrix of
the same resolution (both have the same number of rows and columns) as the
DEM. More specifically I would like to plot a DEM using wireframe and
color each cell/tile based on interpolated surface temperature
measurements. Within the

A question regarding Wireframe in Package Lattice
Hello,
The following code produces a quadrilateral:
q<-matrix(c(1,3,1,2,3,1,2,4,2,1,4,2),nrow=4,byrow=T)
qc<-xyz.coords(q)
wireframe(z~y*x,qc)
I have 2 questions
1) How can i remove the bounding box i.e the cube encompassing the
quadrilateral?
2) Is there any function to get the 2D coordinates of the
quadrilateral actually used in the final plot ? I could manually

how to invert the axes in the wireframe() plot
Dear List,
I am using the wireframe function in the lattice package, and I am wondering if it is possible to invert the default axes orientation for x and y axes... what parameter should I look for?

Lattice wireframe: How to avoid drawing lines around polygons when using shade=TRUE
I am using wireframe from the lattice package, with the shade option set
to TRUE. When I output to PDF or Postscript, a line gets drawn around
each polygon of my surface which causes ugly Moir? effects and doesn't
make sense in my application (think the plot of Maunga Whau--gridlines
don't make sense). This does not happen when I display on the screen--
then I just get the surface as

Lattice: use levelplot as panel for wireframe
Hi,
I want to draw a figure similar to http://dsarkar.fhcrc.org/lattice/book/images/Figure_13_07_stdBW.png
from http://lmdvr.r-forge.r-project.org/figures/figures.html (figure
13.7) . However instead of using a contour plot as a panel for the
wireframe I want to use a levelplot. Can somebody help me with this?
Thanks in advance for any help,
Kind regards,

lattice wireframe within a loop ???
Hi,
I have the following problem. Calling wireframe within a loop results
into an empty window(s)
#generate some data
temp = expand.grid(A = 1:3,B = 1:3)
temp = cbind(temp, y1 = rnorm(9))
temp = cbind(temp, y2 = runif(9))
#plot y1 and y2 in two different windows
for(i in 1:2)
{
wireframe(y1 ~ A*B, temp, shade =T)
windows()
wireframe(y2 ~ A*B, temp, shade =T)
}

[lattice] Increase distance between tick labels and ticks in wireframe plot ("pad")
Hello,
I try to increase the distance between tick labels and ticks in a lattice wireframe plot. Here's a minimal example:
## Minimal example

df <- data.frame(x, y, z)
wireframe(z ~ x*y, df, scales = list(arrows = FALSE, col = "black", font = 1, tck=0.6))

lattice.wireframe missing wireframe
Hello Everyone,
I am using R ver. 2.10.1 (2009-12-14). I installed lattice today via install.packages.
I am doing this minimal example:
M = read.csv("/path/to/csv")
cloud(x ~ y * z, data = M)
this correctly gives me a scatterplot of the csv data which has 3 columns. Every column contains 1800 numeric 0 < values < 1300

plotting planes and lines in wireframe()
Hi R-helpers
I would like to plot some planes which are perpendicular to the x-y
plane, such as x=y. Is there a way to do this in wireframe? I realize
that I am not plotting a function of x, y since there are infinite
number of z's that satisfy the above relation.... Hmm...
Somewhat related, I would also like to plot a line in 3 d space...

3D surface plot with wireframe or persp?
Hello Dear,
I have a function, like z=f(x,y), and try a surface plot with this function.
But, on the reference of "wireframe" requires data option, so I generated x
and y, and computed z with them. But, still I have a problem to draw a
surface plot. The code and errors are

Controlling (number of) wires in wireframe
Hi,
I would like to plot a wireframe (library: lattice) of the function f
(x,y)=x*y where x and y are equally evaluated between 0 and 1.
When one uses the option drape=TRUE then each "square" between the
"wires" (lines that build the surface shape) gets a certain color. A
perfect wireframe plot of a continuous surface would be, if you
(almost) can not distinguish

Lattice wireframe or cloud plot with different colours by a group
I have a question about wireframe 3-D plots and how to apply colors. I have
a large dataset of river flow (m^3/s) over time, and I have coded these
flows based on their height. I would like to produce a wireframe plot that
colors the graph based on the flow code, i.e. I would like high flows to be
red, medium to be green and low flows to be blue. Here is some sample data
with the basic
