selecting a group of points from a scatterplot?
Hi everyone, is there a way/package in R that would allow me to select a group of points from a scatterplot by drawing a circle around them or some such? I can use 'identify' to pick individual points, but that gets tedious if one has more than 10-20 spots. I can easily select spots within a rectangle defined by picking points using identify... but a simple rectangle sometimes will

movie3d in rgl object 'movie' not found
Hello, I am trying to save a .gif movie using movie3d from the package {rgl}. I am using the following code combined with the globe example on the ?movie3d page. I've installed ImageMagick and the directory seems to be working properly, i.e. when I do Sys.getenv("PATH"), C:\\Program Files (x86)\\ImageMagick-6.7.0-Q16 shows up. #### library(rgl) open3d() lat <-

movie3d function in the rgl package
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

selecting points on 3D scatterplots
Hello Everyone, I am new to R and need some help. I have a matrix of x,y,z coordinates that I would like to interactively plot in 3D and then using the cursor select points on the plot and have the coordinates sent to a matrix. I am using the rgl package to plot the data at the moment because it allows me to rotate and zoom. I also tried cloud and scatterplot3D. I am looking for a function like

3D plots with data.frame

Can a dynamic graphic produced by rgl be saved?
Dear r-helpers, Can one save a dynamic graphic produced by rgl, e.g.: open3d(); x <- sort(rnorm(1000)); y <- rnorm(1000); z <- rnorm(1000) + atan2(x,y); plot3d(x, y, z, col=rainbow(1000), size=2) as a dynamic figure that can be embedded in a pdf? _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box 400400

convert command not found in movie3d (rgl package) in Mac OS X
Dear list, I gave up trying to fix my movie3d (rgl library) issue in my PC (completely black gif/png file) and went ahead and installed MacPorts and ImageMagick onto my iMac (OSX ver 10.6.8). I think ImageMagick is successfully installed in its default location (under /opt/local), and I ran movie3d but I get the following error: Error in system("convert --version", intern = TRUE) : ?

3d interactive video using the rgl package
Hi all, I've been using the 'rgl' package to visualise in 3d the water temperature recorded by a glider deployed off the coast of Australia (see snapshot attached). Using the writeWebGL function, I'm able to produce an html file of the scene with which I can then interact (e.g. zoom in/out, rotate) in my web browser. In R, I have created another scene that includes a loop

Opening a web browser from R?
Hi, I was wondering if there's a way in R to open a web browser (such as Internet Explorer, or Firefox or whatever). I'm doing some analyses that have associated urls, and it would be nice to have the ability to directly open the relevant page from within R. I was looking at the help for 'url' and I can see I can probably access the information I need and display it in my

persp3d and rgl.viewpoint for rotating 3D plots
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

Tinn-R editor question: saving syntax colour options.
Hi, after reading about it in the forum, I tried the Tinn-R editor (in WinXP) running R 2.5.0... nice one! However, I am trying to change the syntax-colouring from the default to my own preferences... and I can do that, but my options don't appear to be saved and get lost when I close Tinn-R. I've searched help menus, and google... and I can't find how to make sure my

Playing with rgl: a Youtube video
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

read.table & readLines behaviour?
Hi, I have been using 'read.table' regularly to read tab-delimited text files with data. No problem, until now. Now I have a file that appeared to have read fine, and the data inside looks correct (structure etc), except I only had 15000+ rows out of the expected 24000. Using 'readLines' instead, and breaking up the data by tabs, gives me the expected result. I do not

Transform plot3d grafics in to executable files
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

Calling R from a Perl script: much slower?
Hello list, I use R for microarray analysis. One procedure I use takes a large matrix, and loops through it looking for specific rows, does an operation with them, and outputs a result (single row) as a row of another matrix. The loop goes on about 25000 times. When I run the loop directly from the R console itself, it takes about 3 minutes in my computer. I'm ok with that. Now,

how to display a string containing greek chrs and variables
I'm trying something that I thought would be pretty simple, but it's proving quite frustrating... I want to display, for instance, the correlation coefficient "rho" in a graph. I can do something like: text(x, y, paste("rho =", cor)) where cor would be my previously calculated correlation coefficient, and x and y the coordinates. Obviously that displays

rgl: insert pauses in animation sequence / movie formats other than gif?
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,
