Hello,
I have been experiencing an odd error with the RGL package that I cannot
figure out. I have searched without luck for fixes to this problem on
Rseek, Google, and the R-help-list.
RGL used to work on my machine about a month ago. It was a very useful
tool. The graphics device will not initialize now, and I cannot figure out
why.
When I try to load the package using ...
library(rgl)
... I get a warning message:
Warning messages:
1: In rgl.init(initValue) : RGL: no suitable visual available
2: In fun(...) : error in rgl_init
I also notice I cannot open a new rgl device:
open3d()
Error in rgl.open() : rgl.open failed
I am on MacOS 10.6.5. X11 is installed and is working to my knowledge.
Are you running R (in a console) or R.app (the GUI)? Does rgl work in
the other one? (They use different drivers. In a console, rgl will use
the glx driver, in R.app it will use agl. It's possible support for agl
has changed or gone away; I only have 32 bit MacOS 10.5.x, so I can't
see what's going on in 10.6.5 or in 64 bit.)

Does anybody have any suggestions to figure this problem out? I tried
reinstalling the RGL package (v0.92.794), I tried removing all but the base
R packages, I tried installing from both source and binary, I tried
re-installing R (v2.12.0). No luck with any of these ideas.
I'm appending my session info and installed packages:
sessionInfo()
R version 2.12.0 (2010-10-15)
Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit)
locale:

attached base packages:

Thanks,
