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.) Duncan Murdoch
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:
