[opensuse] Determining the Version of SUSE

I just obtained an HP 2133 with Suse. How can I determine the exact version of Suse? I would like to install R (http://www.r-projects.org) which has rpms for SUSE. Can I use yum? I'm used to Fedora and trying to become familiar with Suse. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
