similar to: Exporting an rgl graph

Hello Everyone,   Learning about R and its wonderful array of functions. If it's not obvious, I usually try to find out what a function stands for. I think this helps me remember better.   One function that has me stumped is "sink." Can anyone tell me if this stands for something?   Thanks,   Paul         __________________________________________________ [[alternative HTML

Hi, I have a question about exporting interactive 3D plots. I use the following code to plot a contour of a trivariate normal distribution: library(mvtnorm) library(rgl) library(misc3d) n=25 x=seq(-3,3,length=n) X=cbind(rep(x,each=n**2),rep(rep(x,each=n),n),rep(x,n**2)) p=array(dmvnorm(X,sigma=diag(3)*0.5+0.5),c(n,n,n)) contour3d(p,x,x,x,level=mean(p)) lim=c(-3,3)

Hi, I am trying to install the misc3d package on a Windows (XP) installation of R 2.0.1 using install.packages("misc3d") but with no success. I have used this approach with other packages OK, but for misc3d I get the following output... trying URL `http://cran.r-project.org/bin/windows/contrib/2.0/PACKAGES' Content type `text/plain; charset=iso-8859-1' length 27996 bytes

Hi the list, Using misc3d, we can export 3d dynamic graph in pdf format. Is it also possible to export these graph into a format that we can publish on the web?

Hi, I am trying to load the library(ks), but I am getting the following error: Loading required package: KernSmooth KernSmooth 2.22 installed Copyright M. P.

Hi the list, I would like to draw some lines with misc3d. I find a lot of tools to draw surfaces, but nothing for simple line... Is it possible? Note that I know that it is possible to draw lines with rgl (using lines3d), but I need to do it with misc3d to export the drawing in .asy format. Any solution? Christophe

Hi, I'm trying to make sense of the image3d plots in misc3d. Unfortunately I can't find any authors on the help pages of the function to e-mail directly. In the following toy example, I'm puzzled as to why (1) the positions of the image plot on the axes include negative values when I think I've specified all to be 1:3 and (2) the logic that needs to be adhered to in order to

I'm making some 3D plots with contour3d from misc3d and wireframe from lattice. I want to view them from below; i.e. the negative z-axis. I can't figure out how to do so. I would like my point of view looking up from below, with the z, y, and x axes positive going away. Can anyone tell me the correct settings for screen to achieve this? Here is what I've found so far:

I am looking for examples of how to plot with contour3d() to a PNG or PDF file, add axes and other elements to the isosurface plot, and use contour3d in conjunction with lattice. Regarding lattice, I'm not necessarily looking for conditioning on the data shown in the isosurface plots, just a way to show multiple plots in one figure and label them. I am new to the packages misc3d and rgl.

Hello everybody, I would like to solve the problem described below in R (if possible). I am very new to R and have therefore no idea what to even look for in the docu. Therefore, if someone could tell me if this is possible in R and where I might find the respective docu then I would already be very thankful. I have a large set (a few million) of points in 3D. I would like to create a

Hey, Is there any function plotting several "implicit functions" (F(x,y)=0) on the same fig. Is there anyone who has an example code of how to do this? The contour3d function in the misc3d package only work with the functions with three dimensions. Thanks a lot. Many thanks for your help. KnifeBoot [[alternative HTML version deleted]]

I think I just saw a thread go by on " how do I make interactive PDF from rgl output" but I ignored it at the time and can't seem to find consensus result on google. Essentially I wanted to create pdf or other output to share a 3D plot and let viewers interact with it but it still wasn't clear on easiest way to do this. Is this 2009 page the best reference?

Do you know of any references that verify the accuracy of R for basic statistical calculations and tests. The results of these studies should indicate that R results are the same as the results of other statistical packages to a certain number of decimal places on some benchmark calculations.

Hi people, I need to prove the good quality of numerical accuracy of R. Anyone knows a paper or anything else comparing R to other statistical softwares in terms of numerical accuracy. I've made a long search about that but I found nothing. Please help me!! Thanx, Talita Leite ------------------------------------------------- Este e-mail foi enviado pelo Webmail da UFAL IMP:

Hi, When plotting the density estimation with DrawDensity3D-function (in package VecStatGraphs3D) it often happens that the end product ie. layers are not intact , see figure in the link: https://www.dropbox.com/s/vzyaiu0vso8hjw2/20623868_10213333234554853_1371245353_n.png?dl=0 Can we somehow effect on that an get intact layers? -- Atte Tenkanen

Hi all, How do I visualize a contour of a tri-variate normal distribution? I just like to see the ellipsoid very much. I hope there is a easy way or existing method in R. Thank you a lot! Michael. [[alternative HTML version deleted]]

I saw an ad in the July 2001 Amstat News for a complex sample survey analysis package called Wesvar. The package has what appears to be a useful feature called a "Workbook" by which the user navigates analysis output. This is a hierarchical tree in which the user may click on a part of the analysis (table, regression fit, descriptive stats, etc.) so as to go directly to that output.

Suppose we start with data("Titanic") mosaic(Titanic, shade = TRUE) How do I combine the dashed box contours of shading_Friendly to indicate negative residuals, with three levels of gray: dark for abs(Pearson Resid) > 4, lighter for 4 > abs(Pearson Resid) > 2, and lightest for bs(Pearson Resid) < 2 ? Thanks, Michael ______________________________________________

So I wanted to export a contour3d object into VTK and it worked well enough, except the top of the ball (the contour) was missing. Example below, or gist here: https://gist.github.com/muschellij2/5126544 rm(list=ls()) require(misc3d) f <- function(x, y, z) x^2+y^2+z^2 x <- seq(-2,2,len=20) ball <- contour3d(f,4,x,x,x, draw=FALSE) drawScene.rgl(ball) ### get the triangles allids

Dear list, I wish to visualise some 4D data as a kind of colour / translucent cloud in 3D. I haven't seen such plots in R (but perhaps I missed a feature of rgl). The easiest option I found would be to export the data in povray's df3 (density file) format and visualise it with povray. The format specification baffles me a little, http://www.povray.org/documentation/view/3.6.1/374/ ;
