Code Languages

Notice how this .Rmd file executes code in bash and python.

knitr can execute code in many languages besides R. Some of the available language engines include:

• Python
• SQL
• Bash
• Rcpp
• Stan
• JavaScript
• CSS

To process a code chunk using an alternate language engine, replace the r at the start of your chunk declaration with the name of the language:

```{bash}
```

Note that chunk options like echo and results are all valid when using a language engine like python.
