similar to: [RGL] Need help to modify current plot

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

I'd like to use rgl.surface (or some other function if more appropriate) to create a horizontal and vertical transparent grey slice (plane) running through both the x and y origins and extending across the z axis, i.e. the 3-d equivalent of the normal 2-d coordinate axes we are all familiar with. The examples for rgl.surface are a bit more complex than what I need and I am having trouble

Hi R users, Does anyone know how to change the size of 3d charts? I'm using surface3d in rgl package, opening a new window each time to display the chart. I want it so that the chart fills the whole window, because when I output it to png, I don't want all the white space around the chart (right now, i'm getting this white "border" around the chart because the chart is

Hi, i was wondering if there is a way to annotate rgl plot, after searching i haven't found anything suitable. I saw function text3d but was thinking more about text on the margin, so not interactive.

Hi everyone, I want to plot a 3D interpolation of the concentration of aquatic organisms. My goal would be to have the result represented as clouds with a density proportional to the abundance of organisms, so that I could fly (well, swim actually ;) ) through the scene and see the patches here and there. Basically, I want to do something like this: http://www.youtube.com/watch?v=27mo_Y-aU-c but

Dear all, Below is some code where I try to get plotmath symbols in an rgl plot. Duncan Murdoch kindly suggested to use a "sprite" for this. As you can see, on can get it to work, but my knowledge about grid and rgl is too limited to perfectly solve the problem. 1) As you can see (please rotate the plot a little bit so that (0,0,0) is "in front"), the quality of the .png

Dear all, I have a question about the plotting of the dynamical orbit by using rgl. My code is as follows: open3d() par3d(cex=2) bg3d("white") for(i in 1:out.length){ ind<-which plot3d(x[1:i],y[1:i],out[,"z"][1:i],xlim=c(-10,10),ylim=c(-10,10),zlim=c(-10,10),col="red",cex=2) Sys.sleep(0.0001) } ,where x,y,out[,"z"] are the position of the object in

Dear users, I'm trying to produce a 3d bar plot but the x and y dimensions have categorical data -- so I only want 3 points on each axis. So I try: require(scatterplot3d) mymat<-data.frame( x=c(1,1,1,2,2,2,3,3,3), y=c(1,2,3,1,2,3,1,2,3), z=c(1,2,3,4,5,6,7,8,9)) scatterplot3d(mymat, type="h", lwd=5, pch=" ", xlab="xlabel",

Hi All, Does anyone know of a function to plot a regression surface for two predictors? RSiteSearch()s and findFn()s have not turned up what I was looking for. I was thinking something along the lines of: http://mallit.fr.umn.edu/fr5218/reg_refresh/images/fig9.gif I like the rgl package because showing it from different angles is nice for demonstrations. I started to write my own, but it has

Hi all! I'm very new to R, and I'm having trouble figuring out how to go from a file of points that I have to a 3d surface plot of the data. I typically have something like this: X Y Z 0.005 0.023 34.45 0.0035 0.63 28.48 . I've tried looking at the persp and wireframe packages, and the rgl package, but I can't seem to figure out how to

Hi Folks, I'm trying to get rgl.Sweave to produce plots with transparency. However, it just seems to produce opaque plots when pdf is the output type. Perhaps this is a known issue? I'll just use .png in the meantime, but wanted to see about this, as I didn't see it in the documentation (though it's possible I missed it). Thanks, Allie \documentclass{article} \title {rgl

Hi, I am applying the following code to map pca loadings onto a 3d grid, my problem is this - the output only plots the spheres in the requested color (in this case "red") for the first argument. The sphere from the second argument appear as flat dark circles. Also the text3d() command only seems to work for a couple of the positions, with no text added in most cases. Could anyone offer

Dear list, I'm using the function "movie3d" in the package "rgl" to create a .gif animation of a 3d graphic. The program "ImageMagik" is working properly, R packages are working, basic examples available in the manual also working fine. Problem Solved: when I tried to create more complex movies, i.e. combining different views and zooming, the R-console crashed

Last week I asked about data ellipses with rgl:::ellipse3d() with lines showing the principal axes. (The goal is a visual demonstration of PCA as a rotation of variable space to component space.) I was trying, unsuccessfully, to use princomp() to generate the PCA axes and plot them using segments3d: > > PC <- princomp(trees) > > sdev <- PC$sdev # component standard

Dear all, The documentation on the function open3d in the rgl package, reads: open3d opens a new rgl device, and sets the parameters as requested. I want the new rgl device (window) to be sized and positioned in a specific place on my screen. So, I try to set the "windowRect" parameter as follows: > library("rgl") > open3d(windowRect=c(100,100,500,500))

Context: I have two or more rgl-based views of a given data set, perhaps fitting different models, or showing different things across views. I want to be able to hand-rotate, zoom, scale one view to something I like, and then show the other views with matching viewpoints and scaling. so that one could flip back/forth among graphs and see only the relevant differences. In 2D, all this usually

Dear R- Users, is there a way to determine the size of an rgl window (rgl.open()) either in advance or afterwards, (without using the mouse, of course) ? Intuitively, one would assume to set the size by: library("rgl"); par3d(viewport=c(0,0,500,500)); #rgl.open(); for example. As the parameter 'viewport' is 'readonly' this results in an

Hi List, I am trying to plot a grid with an overlayed height. I have a dataframe with four variables: x,y,gridvalue,height. The dataframe has 2.5mio observations (ie grid points), I assign colors through the gridvalue using map_color_gradient thus producing: x,y,gridvalue,height,gridcol as variables of the dataframe. The grid dimensions are 1253 x 2001 (=2507253 data points). My attempts with
