### Set up R/Stan on Amazon EC2

A few months ago I posted the script that I use to set up my R/JAGS working environment on an Amazon EC2 instance.

Since then I've largely transitioned to using R/Stan to estimate my models. So, I've updated my setup script (see below).

There are a few other changes:

• I don't install/use RStudio on Amazon EC2. Instead, I just use R from the terminal. Don't get me wrong, I love RStudio. But since what I'm doing on EC2 is just running simulations (I handle the results on my local machine), RStudio is overkill.

• I don't install git anymore. Instead I use source_url (from devtools) and source_data (from repmis) to source scripts from GitHub. Again all of the manipulation I'm doing to these scripts is on my local machine.
