Setting up RStudio Server quickly on Amazon EC2

I have recently been working on projects using Amazon EC2 (elastic compute cloud), and RStudio Server. I thought I would share some of my working notes.

Amazon EC2 supplies near instant access to on-demand disposable computing in a variety of sizes (billed in hours). RStudio Server supplies an interactive user interface to your remote R environment that is nearly indistinguishable from a local RStudio console. The idea is: for a few dollars you can work interactively on R tasks requiring hundreds of GB of memory and tens of CPUs and GPUs.

If you are already an Amazon EC2 user with some Unix experience it is very easy to quickly stand up a powerful R environment, which is what I will demonstrate in this note.

RStudio Keyboard Shortcuts for Pipes

I have just released some simple RStudio add-ins that are great for creating keyboard shortcuts when working with pipes in R.

You can install the add-ins from here (which also includes both installation instructions and use instructions/examples).

It looks like some of the new in-line display behavior is back-ported to R Markdown and some of the difference is the delayed running and different level of interactivity in the HTML document. This makes it a bit hard to call out which RStudio’s improvements are “R notebooks” versus “R markdown”, but it means there is a lot of new functionality available. I’ve updated the video to reflect the subtlty (unfortunately on YouTube that means a new URL as you can’t replace videos).

And some just in case decelerations/clarifications/reminders: this video is not from RStudio (the company), and Rstudio client (the software) is a user interface that is separate from the R analysis system itself.
