RStudio Server

RStudio Server is a Linux server application that provides a web browser based interface to the version of R running on the server. RStudio Server makes it possible for users to remotely access RStudio using a web browser.

Follow these steps to install RStudio Server so that it works with Oracle R Enterprise:

From a Linux terminal window, download RStudio.
Create configuration files rserver.conf and .Renviron so necessary environment variables are recognized in the RStudio environment.
1. Create rserver.conf:
```
sudo vi /etc/rstudio/server.conf
rsession-ld-library-path=R_HOME:ORACLE_HOME
```
  A typical value for R_HOME is /usr/lib4/R/lib; a typical value for ORACLE_HOME is /u01/app/oracle/product/11.2.0/dbhome_1/lib.
2. Include ORACLE_HOME, ORACLE_HOSTNAME, ORACLE_SID in .Renviron using the bash shell:
```
cd /home/oracle
sudo vi .Renviron
ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1
ORACLE_HOSTNAME=localhost
ORACLE_SID=orcl
 
export ORACLE_HOME
export ORACLE_HOSTNAME
export ORACLE_SID
```
