Dear Tom, Thank you very much for thinking about this. Please see my replies

> Are you using the EPEL R 3.2.3 builds?
I'm not sure what the question means, but I'm pretty sure the answer is no. I
know I built the versions of R I used from source code (i.e., ./configure
followed by make).

[bwittner@kagoshima ~]$ cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
[bwittner@kagoshima ~]$ rpm -q centos-release
centos-release-7-2.1511.el7.centos.2.10.x86_64
[bwittner@kagoshima ~]$ uname -rmi
3.10.0-327.3.1.el7.x86_64 x86_64 x86_64
> Is the NVIDIA driver in play?
I think so. When I execute the command lspci -v, the only block that has
mention of VGA is the following:
07:00.0 VGA compatible controller: NVIDIA Corporation G84GL [Quadro FX 370]
(rev a1) (prog-if 00 [VGA controller])
Subsystem: NVIDIA Corporation Device 0491

Kernel driver in use: nouveau
> What version of the NVIDIA driver are you using?
Since the output of lspci above said "Kernel driver in use: nouveau", I
executed the command modinfo nouveau, getting the following output:
