In gadenbuie/epoxy: String Interpolation for Documents, Reports and Apps

To use epoxy in your R Markdown document, create a new chunk using the engine of your choice. In that chunk, write in markdown, HTML, or LaTeX as needed, wrapping R expressions inside the delimiters for the epoxy chunk.

```{epoxy}
The average speed of the cars was **{mean(cars$speed)} mph.**
But on average the distance traveled was only _{mean(cars$dist)}_.
```

The average speed of the cars was **{mean(cars$speed)} mph**.
But on average the distance traveled was only _{mean(cars$dist)} ft_.

epoxy is built around glue::glue(), which evaluates the R expressions in the { } and inserts the results into the string. The chunk above is equivalent to this call to glue::glue():

glue::glue("The average speed of the cars was **{mean(cars$speed)} mph**.
But on average the distance traveled was only _{mean(cars$dist)} ft_.")

One immediate advantage of using epoxy instead of glue::glue() is that RStudio's autocompletion feature works inside epoxy chunks! Typing cars$ in the chunk will suggest the columns of cars.
