I've had a request to downgrade R on one server, to match three others (someone who's just left had important scripts, and I assume they break going a full subrelease...). The server they want downgraded is running 4.1.0-5; the others are running 3.0.1-1. ALL are CentOS 6.5, yet yum downgrade tells me "only upgrade available", and yum list R-core-3.0.2\* gives me "no matching packages". Anyone know what's wrong here? mark
