[Rd] RCmdr on Linux with R 2.0.0 over VNC can't use GLX
Hello, I'm a admin over at Harvard University and I have quite a few users that use R predominately over VNC. In the past this has not been an issue, but after upgrading to R 2.0.0 they can no longer use RCmdr over VNC. When trying to use the package, they see the following: library(Rcmdr) Loading required package: tcltk Loading required package: zoo Loading required package: strucchange Loading required package: sandwich Loading required package: rgl RGL: GLX extension missing on server Error in firstlib(which.lib.loc, package) : error rgl_init Segmentation fault (core dumped) The same commands work fine when using a non-VNC display. Is it at all possible to modify RCmdr to not use GLX when it is unavailable?

Is it at all possible to modify RCmdr to not use GLX when it is unavailable? This looks like a problem with the rgl package rather than Rcmdr per se. I think it's probably not possible to modify rgl to do anything useful when GLX is unavailable, so what is needed is for rgl to fail more gracefully, or for it to be possible to load Rcmdr without rgl. For future reference: with most packages it's best to start by contacting the package maintainer, rather than posting to R-help or R-devel. I've cc'd the Rcmdr and rgl maintainers on this. You can see the maintainer listed by using library(help=Rcmdr) library(help=rgl) Duncan Murdoch __ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

The issue is with package rgl, and we need to talk to the maintainer, John Fox (Cc:ed here) John: I am having problems too. On AMD64, rgl was flaky under Fedora Core 2 and crashes everytime on FC3. It also crashes on 32-bit FC3 using Xvfb. Could you please make it optional: few users will actually want it in every session.

Dear Brian and Bob, That's too bad: I had hoped to increase the use of 3D graphics in the Rcmdr package, for example for 3D added-variable and component+residuals plots. In fact, I'd like to see improvements to the rgl package so allow such things as plot controls and point identification. In any event, it shouldn't be hard to make rgl optional, and I'll do that in the next release of the Rcmdr package, probably via something like options(Rcmdr=list(rgl=FALSE)).
