...ameters, with no luck... I would like to generate a movie from a 3D object (code below), where the vortex A is closer to the observer, and then the object rotates and the B vortex gets closer. I would like to capture this movie to a file. By the way, I am not being able to insert unicode text with text3d. rgl 0.82, R 2.8.1, Windows Vista. Any help would be appreciated. Code follows: library(rgl) open3d() coord.1=c(0,100,0) coord.2=c(100,100,0) coord.3=c(100,0,0) coord.4=c(0,0,0) coord.5=c(50,50,70) pyrcolor="red" triangles3d(rbind(coord.1,coord.4,coord.5),color=pyrcolor) triangles3d...

Dear all, I have a quiet simple problem (shared by a collegue) but no solution at yet. The arguments I use in bbox3d or text3d do not have any effect on the graph. I need to use 'cex' and 'zlim' but It does not work. Maybe my problem could appear trivial but I have spent a lot of time on that. If you have a solution, please let me know! stephane [[alternative HTML version deleted]]

...2,2),zlim=c(-8,8), phi=30, theta=-30,nticks=8,ticktype="detailed") I've tried the text() function : text(x=0,y=0,z=0,texts="O") It returns the following error message: >Error: evaluation nested too deeply: infinite recursion / options(expressions=)? I've seen that text3d from the rgl library could add text on a plot3d object or a persp object. But when I try this: text3d(x=0,y=0,z=1,texts="O") The result is that R opens a new window with the string "O" printed in the new window. And no text is added to my previous persp plot. I've seen that...

Hi, I am applying the following code to map pca loadings onto a 3d grid, my problem is this - the output only plots the spheres in the requested color (in this case "red") for the first argument. The sphere from the second argument appear as flat dark circles. Also the text3d() command only seems to work for a couple of the positions, with no text added in most cases. Could anyone offer any suggestions? g.pca <- prcomp(RtG , retx = TRUE) scale <- 0.4 bg3d("black") amp <- 6 zlim <- amp*range(z) zlen <- (zlim[2] - zlim[1])*100 colorlut &lt...

Hello I was wondering if anyone has been able to change the pch value for points in 3dplot()? I am able to change point colors just not symbol types. I have included a portion of my code below. I realize this won't work outside of my script, but thought, maybe there is something obvious that I am doing wrong. Also is it possible to utilize the interactive feature of 3dplot in a

I want to print characters from the symbol font (or perhaps even Wingdings) in an rgl 3d plot, but I am having no luck. So, what do I have to do in order to get this snippet to print out a character from the symbol font? library(rgl) open3d() text3d(1,1,1,"a",adj=c(0.5,0.5),cex=10,family="symbol",font=1) I am on Windows XP with R 2.9.1.

I think it is an easy question but i haven´t found a solution since I am r beginner. I did this plot3d(PCoA, type="p", col=rainbow(1000),size=5) text3d(PCoA, text=Nam) How can I save it including the labels to a jpg-file? Thanks in advance.

Hi, i was wondering if there is a way to annotate rgl plot, after searching i haven't found anything suitable. I saw function text3d but was thinking more about text on the margin, so not interactive.

hello, I wish to create some 3d scatter diagrams visualising different grouped data set by a given field in the database. I tried the scatterplot3d package, as well as the plot3d and scatter3d functions (both within the rgl resp. Rcmdr package). My first question is, whether is it possibe to group data in the scatterplot3d and plot3d, because I did not succeed to use the groups = ...

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,

Hello R users, I am a newby using R 2.5.0 on a Apple Power Book G4 with Mac OS X 10.4.10. Sorry that I ask again such stupid questions, but I haven´t found how to label the points created with plot3d (rgl). Hope somebody can help me. Thanks in advance.

Fellow R users, I often use « text » to annotate plots in 2 dimensions. Having grown up to 3 dimensions recently, I am looking for a similar function. Could anyone provide code for how to annotate points in a 3-d plot? Your help is greatly appreciated.

Hi, I am trying to compare two 3D plots. For that, I am trying to use the "pch" parameter in the "points3d" function, but it is not working. Is it implemented? Any suggestion? Here goes a reproducible code. I wanted the second plot having different symbols for the points. x <- rbind(matrix(rnorm(100, sd = 0.3), ncol = 2), matrix(rnorm(100, mean = 1, sd = 0.3),

Hello, I am trying to plot selected data points to a preexisting persp plot that satisfies a condition. I used the following statement - text(coords[,1], coords[,2], names(act[which(act > 8.75)]), cex=0.7) But I get all the points labeled, instead of the points that satisfy the condition specified. Is there any way to plot only the points I want? Also can this be done using

Hi There, I'm attempting to plot 10 values on a three-dimensional PCA with text labels next to each point. While i have no trouble doing this on 2D plots using the 'text' or 'textxy' function, I cannot find a function to do this on a 3D plot. I am using princomp for my PCA: >PCA<-princomp(eucdata, cor=TRUE) >PCA$scores [,1:3] # the three principal components i
