RStudio can be configured by adding entries to 2 configuration files. It may not exist by default and you may need to create
/etc/rstudio/rserver.conf /etc/rstudio/rsession.conf
If you need to add additional libraries to the default LD_LIBRARY_PATH for R sessions. You have to add the parameters to the /etc/rstudio/rserver.conf
Step 1: Enter External Libraries settings
For example, you may want to add GCC-6.5 libraries
# Server Configuration File rsession-ld-library-path=/usr/local/gcc-6.5.0/lib64:/usr/local/gcc-6.5.0/lib
Step 2a: Stop the R Server Services
# /usr/sbin/rstudio-server stop
Step 2b: Verify the Installation
# rstudio-server verify-installation
Step 2c: Start the R Server Services
# /usr/sbin/rstudio-server start # /usr/sbin/rstudio-server status
(Make sure there is no error)
