Answer 1

A popup titled "RStudio Initialization Error" appears with message "Unable to connect to service". To fix it, I tried appending the following to /etc/profile so that Revolution R is picked up by RStudio Server Pro sessions for every user: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/RRO/RRO-8.0.3/R-3.1.3/lib64/R/lib:/usr/local/lib64.
