Plotting irregular grid as image or persp
Hi,
I have an array of 2d node locations and an array triangles, and would
like to plot something like a image or persp.
An example of doing it with rgl is:
library(ncdf)
library(rgl)
# wget http://www.maplepark.com/~drf5n/extras/teapot.nc
teapot<-open.ncdf("teapot.nc")
z<-get.var.ncdf(teapot,"tris")
l<-get.var.ncdf(teapot,"locations")

wireframe() display a graph with two colors, not a gradient.
Hi all,
I'm quite new to wireframe, essentially what I want to do is display a graph, and z-values > 1 would be yellow and those < 1 would be blue.
This is a bit of my data.

Substituting functions in package - Lattice
Hi,
I'm trying to learn how a package works but substituting a
parituclart function with my own (basically the original one with
some debug statements).
The package is lattice and the method is "print.trellis" which is a
S3 method and is not visible.
To replace this, i sourced a file with the rewritten print.trellis,
and the old one was replaced.
However, i get this error

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

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

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

From my homework, the persp function only works with evenly spaced data points with the z data beeing in a matrix. my data is not in that format.

[lattice] Increase distance between tick labels and ticks in wireframe plot ("pad")

I try to increase the distance between tick labels and ticks in a lattice wireframe plot. Here's a minimal example:

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

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)
}

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).

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?
Best regards,

how to plot two surfaces with lattice::wireframe
Hi all,
I'd like to plot the Real and Imaginary parts of some f(z) as two
different surfaces in wireframe (the row/column axes are the real and
imag axes). I know I can do it by, roughly speaking, something like
plotz <- expand.grid(x={range of Re(z)}, y={range of Im(z), groups=1:2)
plotz$func<-c(Re(f(z),Im(f(z))
wireframe(func~x*y,data=plotz,groups=groups)
But that seems like a

Altering the cube around a wireframe plot.
I'm trying to create a 3D plot using wireframe with certain parts removed. I would like to get rid of the part of the outer cube that crosses over the plot leaving the back two walls and the axes. It would also be useful to put lines in the plot separate from the wireframe call. I've looked through the documentation and have not been able to find such a request. Here is my code

wireframe
I've been using lattice/wireframe succesfully to visualize some data.
I have one question.
I want to be able to change the viewpoint ( i.e. rotate the plotted
figure a bit left or right or up and down )
Is there a way to do that?
Or is there some other package around that could help?
Thanks.

Wireframe, custom x-axis values
Hi,
Im plotting some data with wireframe() like so:
wireframe(result ~ u * r, myData, scales=list(arrows=FALSE))
However, I would really like to display something different for the displayed values of "u" rather than the actual values.
This is because my u-values are a sequence of quantiles of myData, and I would like to display the quantiles used (e.g. "0.8 0.85 0.9
