The asis engine allows users to write markdown within chunks. These
chunks can then be conditionally rendered using parameters defined in
the YAML or elsewhere in the document.
By assigning the addin a keyboard shortcut, the addin gives the user a
shortcut to the asis engine. The asis function is useful when the
author intends to create different texts from the same document. For
example, a teacher may want to render a version with a prompt for
students and another version with solutions.
```{r toggle_solutions}
solutions <- TRUE
```
What is half of $4x$?
```{asis student_prompt, include = !solutions}
Write your answer here:
```
```{asis instructor_solutions, include = solutions}
Correct answer: $\frac{4x}{2}= 2x$
```
If the object solutions takes the value FALSE, then the first chunk,
student_prompt, is rendered. If solutions takes the value TRUE,
then the second chunk, instructor_solutions, is rendered.
