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 dis...

lattice.wireframe missing wireframe
...day 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 when I want to plot the corresponding wireframe via wireframe(x ~ y * z, data = M) The box and axes are set up correctly, only the actual plot content is missing. Wireframe returns without error. Any hints on how I could debug this? Or am I doing something wrong / addtitional config needed? Thanks in advance, Michael Bach

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, te...

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...

cloud() works but wireframe() is blank
Per the message from Alexander Nervedi, 29 April 2006: > I have to be making a riddiculously silly ommission. > when I run the fillowing i get the cloud plot ok. But I cant figure > out what I am missing out when I call wireframe. > Any help would be appreciated. > x<-runif(100) > y<-rnorm(100) > z<-runif(100) > temp <-data.frame(x,y,z) > wireframe(x~y*z,temp) > cloud(x~y*z,temp) There is something funny about the way wireframe treats a data frame object created using "data.frame&q...

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 points on it: wireframe(z ~ x * y, data=dem, aspect = c(1, .5), scales = list(arrows = FALSE), panel.3d.wireframe = function...

[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 x <- y <- z <- c(1,2,3) df <- data.frame(x, y, z) wireframe(z ~ x*y, df, scales = list(arrows = FALSE, col = "black", font = 1, tck=0.6)) I tried the axis.components option (http://r.789695.n4.nabble.com/Lattice-distan...

plot3d, wireframe, persp help
...am trying to get a surface plot of a data set that looks like the following, 1 2 5.6 5 9 2.4 9 8 9.8 ... to (60,000 rows down) 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. the wireframe fxn gives me an error, no applicable method for "wireframe" the plot3d fxn I got working thanks to Scionforbai's help. However it does not represent the data like wireframe or persp would. Any help would be appreciated. thanks --------------------------------- [[...

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 clunky way to...

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...

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 ################################################## mle_beta0=64.43707; mle_beta1=-24365.16; # generating for the requirement of "wirefra...

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 abl...

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, Simone Gabbriellini

different colors for two wireframes in same plot
Hello R, According to: g <- expand.grid(x = 1:10, y = 5:15, gr = 1:2) g$z <- log((g$x^g$g + g$y^2) * g$gr) wireframe(z ~ x * y, data = g, groups = gr, scales = list(arrows = FALSE), drape = TRUE, colorkey = TRUE, screen = list(z = 30, x = -60)) i have two wireframes in one plot. How could i change the color of the top - one to transparent (or only the grid). I want to give insight...

Lattice: how to have multiple wireframe nice intersection?
Hello, This code builds a simple example of 2 wireframes : require(lattice) x <- c(1:10) y <- c(1:10) g <- expand.grid(x = 1:10, y = 1:10, gr = 1:2) g$z <- c(as.vector(outer(x,y,"*")), rep(50,100)) wireframe(z ~ x * y, data = g, groups = gr, scales = list(arrows = FALSE)) However, the intersection between the wireframes is not...

Trying to tile wireframe plots (using lattice package)
Hi all, I'm trying to print a number of wireframe plots (generated using the lattice package), and I want them to appear in a two-by two matrix along with some other (standard) plots. In other words I am trying to create a subplot or tiled plot that works for wireframes. I've tried the methods discussed in: http://tolstoy.newcastle.edu.au/...

empty wireframe
Perhaps I am missing something incredibly basic, but I can't get the wireframe function to plot anything other than an empty graph with axes (and the correct scale). Cloud() works just fine, as does scatterplot3d(), and wireframe() works fine for other data sets I have. Are there some data sets that can't be plotted with wireframe()? If so, what are the characteristics...

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.
