Rstudio is a general-purpose Integrated Development Environment that is particularly suited for the language R, and popular among R users. In new Code Ocean, you can access Rstudio as an interactive session.  

The first time you do so, you'll probably need to install Rstudio.

To install Rstudio: 

Click the  Environment & Dependencies icon, switch to Setup Script, and paste the following (if is is not there already): 

apt-get update && \
    apt-get install -y --no-install-recommends psmisc sudo lsb-release && \
    curl https://download2.rstudio.org/rstudio-server-1.1.456-amd64.deb -o rstudio.deb && \
    mkdir -p /etc/rstudio/ && \
    echo server-app-armor-enabled=0 > /etc/rstudio/rserver.conf && \
    dpkg -i rstudio.deb && \
    rm rstudio.deb

 To run Rstudio:

First, if you are not viewing new Code Ocean, click the 'Preview the new CO' icon;

Second, from the interactive sessions dropdown, select Rstudio: 

This will trigger a new run accompanied by the words 'Interactive Session.
Third, when the words turn blue, click them (it is a link):

To launch Rstudio!

Five general caveats about interactive sessions on Code Ocean:

  1. Leaving an interactive session running will continuously use quota until you stop the run by clicking the red square in the screenshot above. 
  2. Every 30 minutes, your interactive session will ask you if you are still there. This is to prevent an idly open tab from exhausting your quota. 
  3. When you open an interactive session, you may be prompted to accept notifications from Code Ocean. If you accept, you will receive this half-hourly reminder in your open interactive tab. If you do not accept, it will pop up in the Code Ocean capsule from which you launched the interactive session.
  4. If you do not actively tell Code Ocean that you are still working, every 30 minutes, your session will end and your work will be lost. Please pay attention to these notifications. 
  5. Work done in an interactive session will not be saved to your /code and /data panes. For the time being, please copy and re-implement any changes you wish to save back to your code and data.
