similar to: 3d graph to show matrix of z matrix values

Dear R users, I have been trying to draw the following 3d graphs: The solid region bounded above by the paraboloid z = 9 - x2 - y2 and below by the unit circle in the xy-plane. I wanted to visualize the solid region bounded by those two graphs. I could draw those two 3d graphs separately, but I could not get those two to work in one single plot. Here's my code for the paraboloid: x <-

Hello, say I have a 2D-matrix (indexed by x and y), which contains z values, which I want to plot over x-y. Either dotted, or if possible as a landscape. I tried around with persp and plot3d (from rgl) and persp3d (from rgl). I sometimes get something that looks good and a while later, when trying some new data I need to worry about that again. Is there something lika a convenience function

Hallo! ? I just want to make a 3D plot of a surface of a cone and want to plot some single points around. ? I tried wireframe but cannot find how to plot single points ? I tried scatterplot3d but there the surface is not simple to plot. And: How can I rotate the point of view by the z-axis ? I tried persp3d but how can I add some single points? ? Example: ? library(lattice) library(scatterplot3d)

Hi, I want to format my axis in my persp3d plot. With my data, which I attached I created a persp3d plot with the following code, which I summarized from different code snippets I found: library(rugarch)library(rgl)library(fGarch)fd <-as.data.frame(modelfit,which ='density')color <-rgb(85,141,85,maxColorValue=255)x <-seq(-0.2,0.2,length=100)y <-c(1:2318)f

Dear R-users, within the rgl-package, I would have a question about the usage of persp3d in combination of rgl.viewpoint. I am not able to figure out how to let a 3D plot rotating around likewise the example in ?rgl.viewpoint. It seems that when I use persp3d(...) I see something on my screen, which is different from what I get when it's rotating. Is there any different behavior between

Is there a way to import a data frame into a workspace? I created a data frame and from my understanding, a data frame is a type of object, and that the workspace stores the current session's objects. Wondering why my data frame is not showing up... Any thoughts/suggestions? -- View this message in context: http://r.789695.n4.nabble.com/data-frame-to-workspace-tp3986415p3986415.html Sent

Dear all, I would like to put two perspective plots into one plot. The help page for ?persp shows how one can add points and lines but not another perspective plot. data(volcano) z <- 2 * volcano # Exaggerate the relief x <- 10 * (1:nrow(z)) # 10 meter spacing (S to N) y <- 10 * (1:ncol(z)) # 10 meter spacing (E to W) ## Don't draw the grid lines : border = NA persp(x,

Hi all, I have following problem : a = b = seq(1, 50000, by=500) v = matrix(0, nrow=length(a), ncol=length(a)) for (i in 1:length(a)) { for (j in 1:length(a)) { d = c(17989*a[i], -18109*b[j]) v[i,j] = t(d) %*% matrix(c(0.0001741, 0.0001280, 0.0001280, 0.0002570), nrow=2) %*% d } } library("rgl") open3d()

Good to hear you've made such progress. Just a couple of comments: - You should use points3d() rather than rgl.points(). The latter is a low level function that may have unpleasant side effects, especially mixing it with other *3d() functions like persp3d(). - There are several ways to draw a flat surface to illustrate your data. Which one to use really depends on the form of data.

Hi R users and experts, I am interested in learning more about the use of 3D plots. Specifically, I want to add points and lines to a surface plot. And get the axes and labels plotted also. Here is what I have tried with an example data set : library(rgl) vol2 <- 2*volcano # Exaggerate the relief library(reshape) mvol2 <- melt(vol2) str(mvol2) # First, persp and persp3d plots do not succeed

Dear R-users, I would like to place two 3D plots side-by-side in a rgl-setting. It would nice to have something like "par(mfrow=c(1,2))" for basic plots, or an array framework for wireframe(lattice) (see example below). I only managed to overlap two persp3d plots. My final idea would be to animate both surfaces using play3d(rgl). Thanks in advance for any help. Best, Carlo Giovanni

Dear All, Thanks a lot for the useful help again. I manage to get it done up to a point where I think I just need to apply some smoothing/interpolation to get denser points, to make it nice. Basically, I started from Duncen's script to visualize and make the clipping along a plane at a slice. Then I map my data points' values to a color palette and just plot them as points on this plane.

Hello all, I use persp3d from the rgl-package to plot a sruface. The typical call is persp3d(x, y, z) With cooridinate-vectros x, y and a function-values matrix z. Now I have different z's, say z_1,...,z_n Question: Is it possible to generate an animation from a sequence of such calls, for different z's? I would like to see how the surface is beeing changed in the time. Thank you

Dear R-experts, Using persp3d(), I plotted a 3d surface. I would like to colour this surface based on the result values (dependent variable) grouped in, say, three to five different ranges. Later, I would also like to paint the same surface based on the range-values of one of the independent variables. Please help. Thank you. Regards, Suresh -- View this message in context:

Dear all, I have tried to plot a triangular matrix with the function persp3d(rgl). for example z=rbind(c(1,NA,NA,NA),c(5,3,NA,NA),c(4,2,9,NA),c(8,6,5,11)) x=1:4 y=1:4 persp3d(x,y,z,color="gray") The two extreme points are not plotted (value=1 and value=10). It seems because the half of the matrix have 'NA' and perp3d need planar quadrilateral face. So I decided to use the

DeaR list, I'm trying to represent some information via 3D plots. My data and session info are at the end of this message. So far, I have tried scatterplot3d (scatterplot3d), persp3d (rgl), persp (graphics) and scatter3d (Rmcdr) but any of them gave me what I'd like to have as final result (please see [1] for a similar 3D plot changing PF by ypred, pdn by h4 and pup by h11). In general

G'day everyone, I've been trying to get an interactive OpenGL plot to work from within Python 2.6 using Rpy2 and the persp3d function. The problem is that the plot seems to freeze upon activation. All interactivity is lost even though it works fine when run from within the R console (version 2.11.1). Is this a known issue? Any ideas as to what might be causing this, or possibly how to fix

Dear expeRts, I am a new user of rgl, below is my first trial to plot a simple function in 3d. I managed to put the axes in the right locations, but: (1) The xlab, ylab, and zlab arguments are ignored; how can I put in axes labels? (2) Since I removed the axes in persp3d() the viewport is too small; is it possible to keep the size of the viewport? (3) The box is not correctly drawn, there

Hi guys, I hit on a problem when I use rgl. Could you try to run the code here in this link and see why the first persp3d gives a red bounding box and the second shows black? http://rafb.net/p/g1i7ur33.html (sorry for not pasting the code here directly but my previous email got filtered by this list so I suspect my code looks like spam to the spam filter) I'm expecting black color to be
