That's not quite true:

Dear all, I write to the community to know if other people expierenced the same problem. I want to save a rgl scene where I plotted a 3d cloud of spheres whose radius is set proportional to a given variable and coloured by another group variable and with 95% ellipsoids for distribution of any group. I had no problem at all for coding but I had two problem when saving the scene (in any format)

Dear Rglers, With rgl, I would like to set marker when a button is pressed, but leave the standard trackball handling otherwise. Thanks to Duncan and Oleg for helping me handling key down. How do I say in a custom mouse handler "after having done your work, forward to standard trackball once only"? The example below shows the idea, but it works only once, then reverts to standard

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

Hi list, I am trying to print a rgl scene. I can do this with rgl.snapshot("test.pnt",fmt="png"), but rgl.postscript("test.pdf",fmt="pdf") does crash R and returns to the linux shell after extented time period. I am running R 2.4.0 on i686 linux mandrake 10.2. Do I need any other R external program to make this work? Thanks Herry Dr Alexander Herr -

Hi! I'm new to R, but have worked with Splus before. I installed several packages in R (R-1.9.1) without problems, but when I try to install rgl (rgl_0.64-13.tar.gz). I get the following, and the package does not install. Any help would be greatly appreciated. I'm running R in redhat 9. Thanks, Enrique ------- [my pc]# R CMD INSTALL rgl_0.64-13.tar.gz * Installing *source* package

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

For use with rgl, I'm looking for a function to draw a plane in an rgl scene that would function sort of like abline(a, b) does in base graphics, where abline(0, 1) draws a line of unit slope through the origin. Analogously, I'd like to have a plane3d function, so that plane3d(0, 1, 1) draws a plane through the origin with unit slopes in x & y and plane3d(3, 0, 0) draws a

*Summary*: The latest Windows binary version of rgl_081.708 from R-Forge has some problem that causes rgl.snapshot() to fail, at least on my system. Thereafter, *all* rgl 3D graphics are rendered without any text labels. The last problem remains even after (a) removing rgl and re-installing from CRAN, (b) re-starting with a fresh installation of all of R 2.7.2. *System*: Win XP Pro A vexing

Hi all, How can I tell RGL to set the center for the rotation to the origin of the coordinate system (0,0,0). It seems that the default is to use the center of the display not the origin of the coordinate system. open3d() lines3d(c(0, 1), c(0,0), c(0,0)) lines3d(c(0,0), c(0, 1), c(0,0)) lines3d(c(0,0), c(0,0), c(0, 1)) TIA Mark ???????????????????????????????????????

Hi, I'm new here. This question concerns the package rgl. Is it possible to change the colour of a set of points drawn with plot3d /without/ removing them from the scene? The idea is to create a presentation of a clustering algorithm, step by step, representing the currently assigned cluster by a colour. Removing all the points with "rgl.pop" and replotting them at each step

Dear all, I tried to install rgl package on my linux machine fc5, I got an error.

I'm running R2.0.1 under Solaris 2.9 on a SunBlade 100. When I installed it, I set things up to use the Sun compilers cc, CC, f95 with the options recommended in the installation and administration guide. Until today, no worries. With all this discussion about R GUIs I thought I'd give R Commander a go. The web page said to install a bunch of packages first, so I did >

Hello Everyone. I?m on a Mac, using rgl. Thanks to all the developers and maintainers on it! If I drag the mouse, I can rotate the view, if I hold down the option key or the ctrl key and drag, I get scaling (though at times I seem to alter the perspective?). Adding the shift key doesn't seem to modify anything. So, what I can't find is a key combination that translates the object.

Hello useRs, I would like to draw a 3D-surface using rgl with a point-like light-source within the scene, that is with finite distance of the light-source to the surface to be lit. >From the help to the 'light3d' command I read: "They [the light-sources] are positioned either in world space or relative to the camera using polar coordinates." which *could* be understood as

Two questions related to creating animated movies with rgl: 1. I've created an rgl scene with 5 different views I want to display in a movie, but I'd like to insert pauses (say, 5 seconds) at each view. How can I do this? I first created 5 userMatrix's, then play3d( par3dinterp( userMatrix=list(M1, M2, M3, M4, M5)), ,duration=2*60/5) ) then tried simply repeating each twice,

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

I?ve installed R 3.7.0 on a new laptop running macos 10.14.5 and have managed to get most of my usual packages to compile from source with a ~/.R/Makevars file that looks like this: CC=/usr/local/clang8/bin/clang CXX=/usr/local/clang8/bin/clang++ LDFLAGS=-L/usr/local/clang8/lib CPPFLAGS=-I/usr/local/clang8/include -I/opt/X11/include/freetype2 FC=/usr/local/gfortran/bin/gfortran

Hello, I'm looking for help putting an interactive rgl package 3d device on the web so that it maintains full functionality. Where should I start? Is it possible? Is there an example I can see? (Note: I'm also looking at putting other normal plots on the web.) I'd like to stay within R as much as possible... I didn't find much online regarding rgl 3d plots. Thanks, Ben

I want to plot points with different colors to show different selections of points in a 3d plot. My problem is that if I plot a red point at a location where already a blue point was plotted, than the point is still blue. Is there a parameter or so which can be used to draw over a existing point? Example: > require(rgl) > open3d() > plot3d(a<-c(1,2,3,4,5),a,a,type="l",
