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

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: '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
'units'

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))

Eliminate border in wireframe plot
How can I eliminate the border drawn by default around a wireframe plot? I've tried using border=NA and box=FALSE to no avail.

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,

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

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

Lattice 3d coordinate transformation
Hello List!
I asked this before (with no solution), but maybe this time... I'm
trying to project a surface to the XY under a 3d cloud using lattice.
I can project contour lines following the code for fig 13.7 in
Deepayan Sarkar's "Lattice, Multivariate Data Visualization with R",
but it fails when I try to "color them in" using panel.levelplot.

wireframe color
Hello, hopefully simple question, but I cannot find the answer. I need to
change the color from the standard default. Still want the scaled colors,
but need different colors for different graphs.
Code is:

drape = TRUE,

adding points to a wireframe
A quick question. I'm trying to plot a surface from a fitted model
along with the original points, as in the following example:
df<-data.frame(expand.grid(100*runif(1:100), 100*runif(1:100)))
df$Var3<-rnorm(length(df$Var1), mean=df$Var1*df$Var2, sd=10)
my.lm<-lm(Var3 ~ Var1*Var2, data=df)
my.fun<-function(x,y) predict(my.lm, data.frame(Var1=x, Var2=y),

Contour lines in a persp plot
Hello folks,
i'm a R beginner and i want to put in a same plot both contour lines
and persp plot.
For example,
fn<-function(x,y){sin(x)+2*y} #this looks like a corrugated tin roof
x<-seq(from=1,to=100,by=1) #generates a list of x values to sample
y<-seq(from=1,to=100,by=1) #generates a list of y values to sample
z<-outer(x,y,FUN=fn) #applies the funct. across the combos of x

grayscale wireframe??
I need grayscale formatting for a wireframe.
The only col.regions that I can find are color palettes are all colored:
rainbow(n, s = 1, v = 1, start = 0, end = max(1,n - 1)/n,
gamma = 1, alpha = 1)
heat.colors(n, alpha = 1)
terrain.colors(n, alpha = 1)
topo.colors(n, alpha = 1)
cm.colors(n, alpha = 1)
The code follows:

wireframe and par(mfrow)
Hello List,
I have some plots with the wireframe() function, and I'd like to
display them in a single jpeg file. I know that par(mfrow=c(x,y)) will
divide my display window in x rows and y columns, and although this
works with plot(), it looks like it's not working with wireframe.
here's my code:

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...
Finally, if you are feeling really brave, I

Layering multiple persp plots
Hi all,
I've got two persp plots with Identical X and Y's, and I'd like to plot them
on the same graph, so that it is obvious where one plot is above the other.
I can't find any mention of this anywhere. Do I need to use wireframe?
Any help is appreciated.
Thanks,

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?

wireframe zlim option
Hello,
I would like to plot a wireframe of a function which is defined on the
unit square using the lattice library (for trellis-like plots). The plot
contains z-values of about 100 (only in the neighborhood of zero) although
most of the z-values are in the range of -let's say- 0 to 10. If I
evaluate this function on an equidistant grid of 25 points on the unit
square the plot quality is not
