Configuring External libraries for R-Studio for CentOS 7

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)
