Issue with R-studio Server installation in RedHat

[lianouw]

Hello,

I am trying to install R Studio Server on my Linux RedHat 7.3 VM in which i don't have internet access. I did as the documentation told to and have installed the EPEL prior to R-studio but i still get the following error :
"Unable to find an installation of R on the system (which R didn't return valid output); Unable to locate R binary by scanning standard locations"
Can you help me ?

Thanks,
Liana

Besides installing EPEL you still have to install R

sudo yum install R
