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

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 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 <-

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

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 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

Hi list, I'm trying to limit the z axis plotted using persp3d {rgl} to a given range. I'm trying the following statement persp3d(g0,pa,D, xlim=range(g0),ylim=range(pa), zlim=range (zbounds),col="lightblue") where g0 and pa are both a range of 20 numbers from 0.05 to 1, and D is a 20 x 20 matrix with values ranging from 0 to 30000. I'm trying to set a cap on the Z

Dear list, there seems to be a problem with the standard location of R?s 64-bit libs at least under openSUSE. I had two user questions regarding the compilation of rpy2 for 64-bit systems. Personally I don`t know rpy2 but maybe someone on this list can decide if the mistake lies on R`s side or on rpy2?s side or in between. R-devel is installed in these cases, I asked. Latest R-base or

Hi all, I am new to python, R and rpy2. I having few errors when I am using 'fisher.test' function where I am struck now. Please help to fix these bugs. My code for fisher.test goes this way *from rpy2 import * import rpy2.robjects as robjects def fisherExact(a,b,c,d): v = [a,b,c,d] m = robjects.r['matrix'](v,2,2) s = robjects.r['fisher.test'](m) return s *

I need to install rpy2 on RHEL6. The version of R in the 6 repos is 3.0, and rpy2 does not work with that version. I installed R 3.3.3 following the directions here: https://oguya.ch/posts/2017-03-18-building-R-on-rhel-6/. But even with 3.3.3 it's still failing. Using pip it fails with: /usr/local/lib64/R/lib/libR.a(CommandLineArgs.o): could not read symbols: Bad value and installing from

Hi - I am having trouble installing rpy2. I have already compiled R as a shared library, but I do not have admin privileges on so I am trying to install rpy2 with: pip install -user rpy2 but I am getting the following error: ======================================== ./rpy/rinterface/_rinterface.c:86:31: fatal error: readline/readline.h: No such file or directory compilation terminated. error:

Hi While installing RPy2, I had curious problems which, if I traced them back correctly, have their root in the way that libR.so find the R installation directory. I wonder if this might be a subtle bug that only causes problems when one has several versions of R on one system but then can be very annoying and cause very strange behaviour. It seems to me that libR.so asks the Unix shell to

Hi, I have some trouble to get the Python bindings RPy2 running with the latest release of R. I'm using Windows. The reason is, that RPy2 looks at certain places for R.dll, as $R_HOME/bin and $R_HOME/lib, but not at $R_HOME/bin/i386 where the dll is located on my machine. So I suspect that the directory structure has changed and the RPy2 team did not notice it. I would like to discuss a

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

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

Dear list, When calling R from C, what appears like a spurious error can be triggered during the execution of chisq.test(x, y). This is happening when the following conditions are met: - x and y are "anonymous" C-level R vectors (they do not have a symbol), but they are protected from garbage collection - x and y are "not too small" (it was experienced as soon as they are

Beside the possible argumentation that with an API elegance and convenience might sometimes be superior to necessity, the suggested pattern ("every program, including R itself, keeping its own flag") does no work too well when the nested embedding of R is involved. A concrete example is: ``` $ R -q > library('rPython'); python.exec('import rpy2.robjects') R is already

(I asked an earlier question on the rpy2 installation to the rpy2 list, the solution there was to edit the setup.py script, but this looks beyond what I can do unless someone tells me exactly what to modify). I have R 2.8.1 on 2 machines running ubuntu 8.04 (packages R-base and R-base-dev, among others, installed using Synaptic) and while the installation of rpy2 went fine on machine1, failed on
