stata_engine {Statamarkdown}

Define a Stata engine for knitr

Description

This function creates a modified Stata engine.

Set up once per session (i.e. document). Ordinarily this is run automatically when Statamarkdown is loaded.

Usage

stata_engine(options)

Arguments

options

options are passed to the engine function when it is actually invoked within knitr.

Details

This function is used as follows.

• stata_engine(options) is a language engine that returns Stata log output.

  The end user should not need to use the language engine function directly. This is the workhorse function that actually calls Stata and returns output.

Value

The language engine function returns Stata code and output internally to knitr.
