similar to: rgl.snapshot only captures a small portion what's visible in the RGL device window on CentOS 7

Dear R-SIG-Fedora, I'm finding that on CentOS 7, rgl.snapshot (a function in the R package rgl, which provides an R interface to the OpenGL 3-d graphics library) only captures a small portion what's visible in the RGL device window. This does not happen with the same R and rgl versions on CentOS 5.3 (see details below). The maintainer of rgl, Duncan Murdoch, responded (see below) that

Tom, Bingo! I followed the instructions in the link below, which allowed me to install the nvidia driver, which fixed the original problem with rgl.snapshot. Thanks very much for all your help. I guess I'll file a bug in the CentOS Bug Tracker so that the nouveau driver might get fixed. I'll also post to R-help so someone with the same problem who only searches R-help and not this SIG

I don't think this is likely, but I'm being thorough. I've now tried the EPEL version of R and it

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi rgl crashes my R session, when resizing the rgl graphic window. I am using Ubuntu Maversick, with dual monitor setup. If I disconnect one monitor, I can resize it "a little bit", but it still craches if I enlarge it to much. I assume that the problem has to do with allocated graphic memory in the kernel, but why is R crashing

Dear People I can't figure out how to fix this problem: rgl won't run under R 2.14.2 (it was working for me before under 2.14.0). The error message is: > library(rgl) Error : .onLoad failed in loadNamespace() for 'rgl', details: call: dyn.load(file, DLLpath = DLLpath, ...) error: unable to load shared object '/Library/Frameworks/

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 RGL experts, I haven't been able to add greek letters to my rgl plot3d. I have tried "expression" with no success. Here is the interested bit: > library(rgl) > cb <- cube3d() > plot3d(cb,xlab=expression(alpha),ylab="",zlab="",box=FALSE,alpha=0.5) The expression(alpha) appears as "alpha", rather than as a greek symbol. I suspect greek

I would like to create a 3d scatterplot that is interactive in the sense that I can spin it on its axes to better visualize some PCA results I have. What are the options in R? I've looked at RGL and perhaps it will suffice but it wasn't apparent from the documentation I found. Any demo scripts available for a package that will work? Mark -- Mark W.

Hello, I tried to use rgl.snapshot and it failed.

Dear Users: I wish to save 3d scatter plots I have generated using the plot3d command in the rgl package. Any image format such as .tiff would work. Can anyone tell me how to do this? Thank you [[alternative HTML version deleted]]

Dear Tom, Thank you very much for thinking about this. Please see my replies below. -Ben > Are you using the EPEL R 3.2.3 builds? I'm not sure what the question means, but I'm pretty sure the answer is no. I know I built the versions of R I used from source code (i.e., ./configure followed by make). > What version of Centos 7? 7.2? [bwittner at kagoshima ~]$ cat

Hi, I am trying to plot a 3d scatter plot using the rgl package but am having trouble. I have a matrix containing x, y and z co-ordinates and a fourth element related to a count variable. I would like to plot the points using plot3d with the sizes of the points related to the fourth element in the matrix. Is this possible with plot3d or do I need to use something else? I include a small example

Hello, I am basically using a script that is designed to first create an rgl 3d scatter plot followed by a barplot on the same data. After this is done, the program is to first save the barplot as a .tiff file then to save the rgl 3d graph as a .png file. Once this is done, it is to repeat this 3d plot and barplot combo with saving 49 more times. The plotting script excerpt will be posted at the

I'm trying to use the rgl package on R-2.7.1 running on top of Ubuntu Hardy amd64. using open3d() and plot3d() I get a plot, but it is not interactive. Furthermore, changes to par3d("FOV"=my.new.value) do nothing. I suspect something is wrong with the rendering engine or interface to it. I do have an Nvidia driver installed and compiz works correctly on the desktop. I've

Buenas tardes. ¿Sabe alguno de vosotros cómo indicar la variable con la que identificar los puntos con plot3d? library(rgl) plot3d(Data$RTLML,Data$JD,Data$SB) Las muestras pertenecen a una de dos categorías, según la variable "Family", pero no sé cómo hacer que me las represente de diferente color. Gracias, Manuel . -- Dr Manuel

I have just encountered the problem with rgl where plot3d figures don't interact with the mouse. My plots zoom in and out with the mouse wheel but the mouse buttons do nothing. I can't rotate the plot. This has been mentioned and discussed here and in other lists before, and the solution is to turn off Ubuntu's fancy graphics. Back in March, Ben Bolker said: """

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",
