How to use RStudio to write a RMarkdown file with Stata commands? - rstudio

Question

My problem is explained in the title. I've tried compiling a sample .Rmd I found here: http://www.ssc.wisc.edu/~hemken/Stataworkshops/Stata%20and%20R%20Markdown/
in addition to looking up various resources online to no avail. While my resource, Doug, was able to compile an RMarkdown, I am getting an error for the MWE below.
The MWE is:
---
title: "Stata and R Markdown (Windows)"
author: "Doug Hemken"
date: "July 2015"
output:
html_document:
toc: yes
---
```{r, echo=FALSE, message=FALSE}
require(knitr)
statapath <- "/Applications/Stata/Stata.app"
opts_chunk$set(engine="stata", engine.path=statapath, comment="")
```
### Descriptive Statistics
A simple example.
```{r}
sysuse auto
summarize
```
The output/error from the RStudio console is:

Answer 1

The page you link to points to this page. There, it is written: "For example, if Stata is installed in /Applications/Stata/, then the path to the Stata executable is /Applications/Stata/Stata.app/Contents/MacOS/", and they give appropriate links for all different flavours of Stata. Also, you need to refer to the executable, not the folder where it is located. If I change your MWE as below, everything works for me (note that I use Stata-SE; you might need to change this for your system).
