Hi, I'm new to R (and math ;) Would somebody please be so kind as to direct me in plotting a 3D sphere? I tried something in the lines of: #### y <- x <- seq(-pi, pi, length=pi*10) f <- function(x,y) { z <- sqrt(pi - x^2 - y^2) #z[is.na(z)] <- 0 z } z <- outer(x, y, f) persp(x, y, z, theta = 120, phi = 30) #### I've also tried: .... make.surface.grid(...) ..

Running: R Version 2.3.1 (2006-06-01), debian stable I'm testing an application that uses rgl (installed with apt-get install r-cran-rgl) but fails, at least partly because that application uses a more current version. There is also a mysterious error msg from Xlib: > library(car) > library(rgl) > iris.mod <- lm(cbind(Sepal.Length, Sepal.Width, Petal.Length, Petal.Width) ~

Hi all I am a complete newbie to this list (just subscribed) and a newcomer to R (an S user from olden times). I have been using scatter3d to create a 3d scatter plot with surface. The graphic is created within the rgl package and I have used rgl.postscript to export it so I can generate a publication quality image. My problem is that the plotted surface is no longer transparent in the

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 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

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've CCd' Duncan Murdoch as the rgl maintainer, but I'm also keen to hear from the broader community of any insights. In rgl my understanding is that there's only one rotation-navigation mode, where you left-click hold and the view pivots abound the centre of the scene. In other tools, including Google Earth, that is the default behaviour but there's also a

hi, all I am looking at R package RGL to draw a colored mesh/surface plot like this one (from matlab). http://www.mathworks.com/access/helpdesk/help/techdoc/visualize/cbar.gif The key features I am looking for is surfaced with grid and color, but not the terrain-like gradient. but I didn't come even close to it after browsing through rgl help file. have anyone drawn something like this

Hello I have a problem on keeping the format when I export a matrix file with the write.table() function. When I import the data volcano from rgl package it looks like this in R: > data[1:5,] [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [,11] [,12] [,13] [,14] [1,] 100 100 101 101 101 101 101 100 100 100 101 101 102 102 [2,] 101 101 102 102 102 102 102

Is there anyway to label axes in 3D plots with mathematical expressions? In the code below, I want to replace "delta_yrsed" with what "\Delta \widehat{yrsed}" represents in TeX, but the [xyz]lab parameters of title3d appear to only accept character strings. require("rgl") fn.delta.yrsed <- function(dist, delta.dist,

Hi, I'm using rgl to generate a 3D surface plot and I'm struggling to get the lighting correct. Currently the surface gets plotted, but is very 'shiny'. On rotating the view, I get to see parts of the surface - but overall I don't see much detail because of the spotlight like lighting. I've played around with the specular, ambient and diffuse but I can't

Hi, I'm currently hunting a bug in the akima library, especially in the code behind the interpp.old function (bi-variate linear interpolation). It is based on a triangulation algorithm, interpolation at a given point needs to know the triangle which contains this point, then the interpolation is a straightforward calculation based on the three vertexes. The problem is: Sometimes the triangle

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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I would be grateful if anyone had suggestions about software that could (1) create 3D surface plots, (2) handle transparency/alpha blending, (3) generate output in some vector graphics format that preserved the transparency. I could also live with a combination of two programs, one to generate the basic figure and another to modify the output

Hej, Calling newuoa (from the minqa package) makes R crash when the package rgl is loaded first. This however only on certain selected data. The data used for testing (saved to 'bugs.R'): xvals = c(1,2,4,5,7,8,9,10,11,12,14,15,16,18,19,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36) yvals =

I don't seem to be able to label the x, y or z axis when creating a 3d chart using rgl.surface. I'd like to have them parallel to the axis line and move with the graph when rotated. Can this be done? Many thanks, J. Retzer [[alternative HTML version deleted]]

Hi all. It's been a long time since I wrote to this list. Glad to see the R project well and working. I am working with a 3D plot similar to this: http://old.nabble.com/file/p26525177/rgl-device.png rgl-device.png The underlying picture is a JPEG image, loaded with the rimage package and coerced to the matrix. Spheres denote control points, collected from this picture and must be

Hello, I have a matrix of simulated data that I want to plot as a 3D surface using RGL. Have followed the documentation carefully, but my plot only contains a weird "single slice" of the data. The actual RGL library and dependance seem fine as all of the demo code plots beautifully. The actual command I'm using is: rgl.surface(x,z,d,
