The need for analytic admins

What organizations need analytic admins? Analytic admins are important for any organization that wants to:

• Modernize their analytic tools
• Take advantage of all their data
• Build analytic products and applications
• Develop a best-in-class data science team

Despite the fact that the need for analytic admins is pervasive in industry, companies rarely list it as a dedicated role. Instead, they require teamwork between data science and IT operations, or they may require data scientists to function as their own admins. But the need is real. Most organizations need help bridging the gap between data science and IT. If you see an opportunity to function in the capacity as an analytics admin, I suggest you take it.

Analytic admins typically have to train themselves and carve out their own career. It is common for data scientists who operate as analytic admins to feel as though they are in no-man’s land. It is natural to feel lost between the worlds of data science and information technology. As someone who had been there, I can say the feeling is disorienting. However, I can also say the value of that position is tremendous. If you feel like you are operating in no-man’s land as you function in this role, just know you are exactly where you need to be.

R tooling and integration

At RStudio, we think about doing data science as a development process that begins with accessing and understanding your data, and then communicating your results. This process is thoroughly explained in the book R for Data Science, by Wickham and Grolemond.

RStudio builds open-source and enterprise-ready products to help you do data science in R. These products include the RStudio IDE, RStudio Connect, and Shiny Server. These are designed to work with open-source R packages like Shiny, R Markdown, and the Tidyverse.

Most of the software that RStudio makes is open source, but enterprises often require additional professional features. Common Professional features are security, authentication, high availability, administration, and load balancing.

R is also used with production environments for hosting web applications, exposing APIs, and automating workflows. R is sometimes integrated into other systems such as data warehouses, Hadoop, and Spark. The role of the analytic admin is to provide tooling for data scientists, as well as to integrate R into production systems.

Linux and R

RStudio products run on Linux, so understanding Linux will help you become self-sufficient, use R with other systems, and build better solutions. We will talk more about what you can do with Linux commands in an upcoming blog post.

There are many resources for learning Linux online. Here is just one offered by the Linux Foundation. Analytics admins need to know how to navigate (e.g., cd, pwd, ls), install Linux packages (e.g., apt-get install), and execute commands as root (e.g., sudo). Also important are tab completion, keyboard shortcuts, and text editors (e.g., vim, nano).

Did you know you can execute basic Linux commands from inside RStudio Server using the Tools > Shell option? You can also execute Linux commands inside the R console with the system function.

Another major benefit of learning Linux is the ability to administer production systems that run with Shiny Server, and the ability to deploy Shiny web applications into production.

Running Shiny in production

There is a growing trend in using Shiny web apps in production analytic workflows. The vibrant Shiny community now spans all verticals including pharmaceuticals, high technology, and finance. For many organizations, adopting Shiny is their first experience in running R in production.

Production environments that depend on Shiny also need analytic admins who can deploy and support these applications. For example, some organizations now have complex Shiny applications that serve hundreds of end users over a cluster of load-balanced Shiny Servers. These applications often go through a standard development > test > production deployment process. New tools are being built for correctness testing and load testing in Shiny. RStudio and other platform vendors are making significant investments in building architectures – like Shiny Server and RStudio Connect – that will help Shiny grow over the long term.

The growth of Shiny opens an opportunity to analytic admins who want to make analytic content available to a wide audience. Shiny apps allow end users who know nothing about R to take advantage of the power of the R programming language. They have the potential to influence decision-makers who can take actions and see results based on the work data scientists share with them. There is an immediate need for analytic admins who understand Shiny and can help support environments that depend on Shiny.

Getting started: Installing RStudio Server

A great way to get started learning analytics administration is to build your own open source RStudio Server on Linux. Building an RStudio Server by hand is the analytic admin equivalent of the Jedi building their own light sabers. It’s a core skill, so you should be able to do it yourself no matter what.

An easy way to get started with RStudio Server is to set it up on Ubuntu with Amazon Web Services. AWS even has an instruction guide for running R on AWS. The core commands of the install are the following four lines of code (note: this installs RStudio Server version 1.0.143).

$ sudo apt-get install r-base
$ sudo apt-get install gdebi-core
$ wget https://download2.rstudio.org/rstudio-server-1.0.143-amd64.deb
$ sudo gdebi rstudio-server-1.0.143-amd64.deb

Of course, your installation is going to require more than just installing RStudio Server. You will probably want use the CRAN repository, install Linux dependencies, add users, and manage R packages. Here is a complete script I used to set up RStudio Server on a simple AWS AMI (ami-efd0428f) using a T2-medium instance. I included instructions from this document on how to install R from CRAN. I also opened port 8787 in my AWS security group so I could log into RStudio Server via my web browser.

### Simple RStudio Server Install
### Based on AWS image: ami-efd0428f
 
## Install R from CRAN repository
$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9
$ sudo add-apt-repository 'deb [arch=amd64,i386] https://cran.rstudio.com/bin/linux/ubuntu xenial/'
$ sudo apt-get update
$ sudo apt-get -y install r-base
 
## Install RStudio Server version 1.0.143
$ sudo apt-get install gdebi-core
$ wget https://download2.rstudio.org/rstudio-server-1.0.143-amd64.deb
$ sudo gdebi rstudio-server-1.0.143-amd64.deb
 
## Add a new user
$ sudo useradd -m myuser
$ sudo passwd myuser
 
## (Optional - may take time) Install common Linux dependencies
$ sudo apt-get -y install libcurl4-openssl-dev openssl libssl-dev
$ sudo apt-get -y install texlive texlive-latex-extra libxml2-dev
 
## (Optional - may take time) Install common R packages
$ sudo Rscript -e 'install.packages("shiny", repos = "http://cran.rstudio.com/")'
$ sudo Rscript -e 'install.packages("tidyverse", repos = "http://cran.rstudio.com/")'
 
## Point your browser to <AWS-instance-IP>:8787

If you don’t want to install RStudio Server from scratch, there are other ways to get started. One is to use a community AMI like this one. Another is to use the AWS Marketplace to install RStudio Server Pro with 1-Click Launch.

Conclusion

Installation is just the first step to administering R. You should also consider the topics of authentication, security, scale, integration, hardware sizing, and configuration. Systems administrators have to do a lot of their own training, and analytic admins are no different. Fortunately, there are plenty of references to help you get started. Here are a few useful references for learning analytic administration for R, RStudio, and Shiny.
