I am using the RGL library in scripted (non-interactive) mode, but wish to give the data analyst an opportunity to exam the 3D plots. The "data analysts" understand the data, but not R. My intent is to provide simple Windows (XP) batch files that call R and automatically pass scripts to it, and thus permit the analyst to easily access graphics without having to cut and paste commands into R. This leads to several questions:
1. Is there any way to save the 3D object so that it can later be restored and manipulated without rerunning the script that created it? This would be the ideal solution, so the analyst can simply pull up the 3D object and examine the data at a convenient time. My hope would be that some method would exist to save as a full 3D object the graphic created using rgl, and subsequent call it up with a command along the lines of r < 3dobject.RData -vanilla. 2. A less optimal solution would be to pause the scripted (non-interactive) session while the 3D object is available. In my Windows environment I've tried various suggestions from the archives without success: a. par(ask=TRUE) (requires creating dummy graphs to obtain a pause, since par3d does not support ask) b. readline(prompt = "Pause. Press <Enter> to continue...") c. pause() in the DAAG package d. scan(). e. locator() 3. Here is a test script (pause.txt) showing the above suggestions fail: require(DAAG) X <- seq(0,10) par(ask=TRUE) plot(X,X) pause() locator(type="p") browser() scan() readline(prompt = "Readline pause. Press <Enter> to continue...") plot(x^2~x) I call this with: r < pause.txt - save The file runs from beginning to end without stopping. 4. I do have a very NONELEGANT solution: cat("Press <Control-C> to end (rather crudely)") while (TRUE){} This does work, but it requires exiting R using control-C, which is not very satisfying. Any help would be appreciated, Steve Shafer [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
