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,

what is the best practice for showing animated ajax spinner? The usual Element.show(''spinner'') has to stick with every form''s :loading. Is there some easier or light-weight method? Because I have this page that can contain upto 100 forms. And with all of those would be 100 hidden spinners. Please suggest something. -- Posted via http://www.ruby-forum.com/.

Hi, A minor announcement. I just added two functions for reading and writing GIF files to my caTools package. Input and output is in the form of standard R matrices or arrays, and standard R color-maps (palettes). The functions can read and write both regular GIF images, as well as, multi-frame animated GIFs. Most of the work is done in C level code (included), so functions do not use any

I'm have a (minor) problem and a question. Problem: The following code creates 5 clusters of dots of different colors. However, I need the second call outside the data.frame call to get the colors to change for some reason. I assume there's an error in the data.frame() call, but I don't know what. Question: Is there is a way to cause the resulting graphic to rotate on it's

Hello, I hope this is the right place to ask for help with a problem I am having with RGtk2 installation with R on Windows XP. I am running R 2.11.1 and have installed the package RGtk2 from CRAN.

I'm having trouble to install RGtk2 (from source) on Mac OS 10.4.11 (R 2.9.0). The GTK libraries (2.12.11) were installed into /sw/lib via fink. Even if I set the GTK_LIBS to that path, the installation program doesn't seem to find it (see below). libglade is there too but not found. If I install the package from binaries, it fails on load. Would anybody know how to make it work?
