How to install R in CentOS 7 under Docker?

Question

I downloaded CentOS from Docker Hub but I am unable to install R with yum or rpm. Commands, such as yum install R, yum install Rcore and rpm install R, do not work.

sh-4.2# rpm --query centos-release
centos-release-7-3.1611.el7.centos.x86_64

How can I install R in CentOS 7 under Docker?

Answer 1

By this Red Hat question, I found the command

yum install epel-release

or with extras

yum --enablerepo=extras install epel-release

after which, the yum was able to find R (600MB with dependencies).

yum install R
