Hi all, could someone tell me which is the best user-friendly free/open source sql database system to use with R, particularly as a back-end for a data-hungry web page? Thanks in advance. Kind Regards Chibisi [[alternative HTML version deleted]]

Dear all, I am using lapply to generate plots by applying a plot function to a list of dataframes. e.g. lapply(dataSet, FUN = plotFunction) Is there a way to call the list item number inside the plot function so that I can identify each graph? Thanks Chibisi [[alternative HTML version deleted]]

Dear all, Does anyone know how to overlay a 3d line on a wireframe plot? I would also like to be able to keep the legend that you get when using the option: drape = TRUE when using the option: shade = TRUE. In addition, I would like to know how to keep the axes while getting rid of the box, I use this: par.box = list(col = NA) to get rid of the box but that also causes the axes to disappear.

Hi all, I am trying to do a 3d plot where the x,y,z axes intersects with the origin (0,0,0) using the plot3d() funtion in the rgl package without success. I looked back at the past archives on this subject and someone suggested using djmrgl package. I searched and found it, installed it but when I try to load it I get the error ... Error in inDL(x, as.logical(local), as.logical(now), ...) :

Hello R-users, I have downloaded and installed a binary version for Windows OS of ImageMagick (ImageMagick6.5.6-10-q16-windows-dll.exe), I have installed the rgl package and i've tried running the following example from ?movie3d() library(rgl) open3d() plot3d( cube3d(col="green") ) M <- par3d("userMatrix") play3d( par3dinterp( userMatrix=list(M,

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,

Dear all, I am trying to read a bunch of csv files using read.table() that are named "test_xxxxxx.csv" where "xxxxxx" has no particular pattern. Is there a way of reading all the files by specifying a truncated file name e.g. "test_" with some wild card characters, or would I have to laboriously create some vector with the "xxxxxx" names and iterate or

Hi, I am looking for a package which allows me to draw arrows (cylinders with cones on them, basically) in 3d images produced with rgl. Is such a thing available? I did notice the 'compositions' package, which contains 'arrow3D'. However, it relies on 'tensorA', which fails to install on my machine with the error message copied below. If anyone can help me fix this

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 list, I'm using the function "movie3d" in the package "rgl" to create a .gif animation of a 3d graphic. The program "ImageMagik" is working properly, R packages are working, basic examples available in the manual also working fine. Problem Solved: when I tried to create more complex movies, i.e. combining different views and zooming, the R-console crashed

Dear all, I am trying to execute the simple example in snowfall http://cran.r-project.org/web/packages/snowfall/vignettes/snowfall.pdf ... require(snow) require(snowfall) sfInit( parallel=TRUE, cpus=2 ) sfLapply( 1:10, exp ) sfStop() I have installed the snow and snowfall packages in R on a machine with windows xp, however, after running the "sfInit( parallel=TRUE, cpus=2 )" line I

I am trying to figure out how to use rgl package for animation. It appears that this is done using the play3d() function. Below I have some sample code that plots a 3D path and puts a sphere at the point farthest from the origin (which in this case also appears to be at the end of the path). What I would like to do is animate the movement of another sphere along the length of the path

I've just posted a demo made with the rgl package to Youtube, visible here: http://www.youtube.com/watch?v=prdZWQD7L5c For future reference, here are the steps I used: 1. Design a shape to be displayed, and then play with the animation functions to make it change over time. Use play3d to do it live in R, movie3d to write the individual frames of the movie to .png files. 2. Use the

Dear all, I have a question about the plotting of the dynamical orbit by using rgl. My code is as follows: open3d() par3d(cex=2) bg3d("white") for(i in 1:out.length){ ind<-which plot3d(x[1:i],y[1:i],out[,"z"][1:i],xlim=c(-10,10),ylim=c(-10,10),zlim=c(-10,10),col="red",cex=2) Sys.sleep(0.0001) } ,where x,y,out[,"z"] are the position of the object in

Hola a todos: Estoy intentando visualizar unos resultados de un programa en R de forma dinámica. Dichos resultados se pueden representar, básicamente, con un plano que gira sobre uno de sus ejes: para dar sensación de movimiento he utilizado la función rgl.clear(), ya que no encuentro los equivalentes en rgl de los parámetros add o new. El problema es que al limpiar la pantalla con rgl.clear la

I'm using the command below on an open3d() object to create a shaded cube. Changes to myScalingFactor do not effect changes in the size of the cube. What is the correct approach?

Hi all, I am considering writing a 3D visualisation package for R. Purposes: - Visualise 3 dimension data - Manipulate the data or series or any other object with the mouse as in any 3D software (3D Studio Max, Lightwave...) - Eventually display more than just 3D objects. Justification: - It's always interesting to plot data before performing any analysis - Manipulating (rotating,

Dear List, I'm trying to draw vector in XYZ with rgl under use of a cylinder3d. Therefore I scale and rotate a basis-cylinder). However, somehow the rotation is wrong as verified by overplotting arrow3d(). Where is my mistake? library(heplots) library(rgl) # ... 2 vectors data=data.frame(row.names=c('X','Y','Z'), x1=c(2,1,5),y=c(4,3,2))

Hello, I did some nice grafics using plot 3d and scatter3d. Is there a, hopefully not too complicated way, to transform these dynamic, three-dimensional and interactive grafics in a kind of executable file? I want to show and send them via e-mail to projekt partners who don`t use GNU R and who are not used to do programming. So the result should be quite comfortable to execute for them in
