Disclaimer: R and RStudio-Server are NOT part of our Essentia Platform. They are third party software that we enable users to install and integrate with AT THEIR OWN DISCRETION. This decision is up to the User and is not required to use any of AuriQ Systems Inc.’s solutions.

Setting up RStudio

If you plan to use our RStudio Integration and you haven’t enabled it yet, you need to:

  1. Go to the AWS Console.
  2. Right Click on your Instance and then click Connect.
  3. Follow the Intructions on the page that appears to connect to your instance via the command line as the ec2-user (replace root@ with ec2-user@).
  4. Once you are logged onto your instance in the ec2-user directory, run sudo su and then bash /opt/essentia/ to install R and RStudio-Server on your instance.
  5. Open /etc/httpd/conf/httpd.conf with your favorite editor. For example, run nano /etc/httpd/conf/httpd.conf.
  6. Add the following lines to the bottom of /etc/httpd/conf/httpd.conf:
    <IfModule proxy_module>
      ProxyPass "/rstudio/" "http://localhost:8787/"
      ProxyPassReverse "/rstudio/" "http://localhost:8787/"
  1. Run apachectl restart.

Accessing RStudio

Go to the UI and then click the RStudio link in the top menu. If you just installed RStudio then you may need to refresh the UI page in order to see the RStudio menu option.

Enter “essentia” as the username and enter the Instance ID of your instance as your password.

You can now use all the capabilities of RStudio directly from your browser.

If you wish to use the command line to access any of the analysis done in RStudio, you need to connect to your instance via the command line as the ec2-user (follow step 3 in Setting up RStudio) and then run sudo su essentia and cd /home/essentia. This will put you in the home directory of the essentia user. This is the directory where all of the user’s RStudio scripts and data are stored.

Running Essentia via RStudio

First, Essentia’s R Integration package must be installed by running install.packages(“RESS”) in R. Then, to access it, you simply need to enter the R command library(RESS). See our R Integration Tutorial to see how to use the RESS package to integrate R and Essentia.
