Stata Source Code Blocks in Org Mode

Org Mode support for Stata

Introduction

Stata is a proprietary statistics program popular in economics and some social sciences. Stata code blocks are partially supported in Org Mode. Basic code evaluation works, but there is no support for graphics or other more advanced org-babel features.

Requirements and Setup

Stata source code blocks in Org Mode requires a working Stata installation, as well as the ESS emacs package. Before configuring Org Mode to evaluate Stata source code blocks you should make sure that ESS is configured correctly, and that you can evaluate Stata code in ESS.

To configure your emacs org-mode to use Stata, you'll need to ensure that org-babel-load-languages includes an entry for it. Typically, org-babel-load-languages will contain many entries. The example below omits other languages.

(org-babel-do-load-languages
 'org-babel-load-languages
 '((stata . t)))
