[R-sig-Fedora] rgl.snapshot only captures a small portion what's visible in the RGL device window on CentOS 7

[Wittner, Ben, Ph.D.]

Ugh.

Below I declared victory, but today I learned that the NVIDIA driver has a problem the nouveau driver did not have. Namely, when using the NVIDIA driver, if I plot a lot of stuff in the RGL window and then using the mouse expand the RGL window, R usually crashes.

One work-around seems to be to
1) close all RGL windows, if there are any
2) call rgl.clear() to create an RGL window
3) re-size that window using your mouse
4) do your plotting

Tom,

Bingo!

I followed the instructions in the link below, which allowed me to install the nvidia driver, which fixed the original problem with rgl.snapshot.

Thanks very much for all your help.

I guess I'll file a bug in the CentOS Bug Tracker so that the nouveau driver might get fixed. I'll also post to R-help so someone with the same problem who only searches R-help and not this SIG will see the solution.

I have not tried it personally, but these instructions seem correct:

Basically, edit the grub2 cmdline to include the extra option:

  rdblacklist=nouveau
