Hugh,
Take a look in /etc/yum.repos.d and see if there are any other yum
config files (*.repo) with enabled repos that may be conflicting with
the config you have in /etc/yum.conf.
You can use:
sudo yum repolist
to get a quick list of repos that are enabled by default.
I would also remove the CRAN config from /etc/yum.conf and unless
there is already one in /etc/yum.repos.d, create another (eg.
CRAN.repo file) just for CRAN with the appropriate config information,
including an explicit 'enabled=1' or 'enabled=0' directive. For
several Fedora/RHEL releases, having separate yum config files, one
per repo, is the preferred model.
An alternative, would be to not use the CRAN repo and add the EPEL
(https://fedoraproject.org/wiki/EPEL
), which has R and other add-on packages that are not part of the
default RHEL/CentOS distribution. Instructions on how to set up and
use the EPEL are on the page linked above.
I am also cc:ing Martyn Plummer and Bob Kinney here, just in case they
have other ideas or are aware of other issues that may be relevant.
HTH,
