The most common use for the
tutorial.helpers package is to allow students to
download their answers after they complete a tutorial. To enable this
functionality, you need to, first, include
library(tutorial.helpers)
within the initial setup R code
chunk and, second, add this line at the end of the tutorial:
```{r download-answers, child = system.file("child_documents/download_answers.Rmd", package = "tutorial.helpers")}
```
When students complete the tutorial, they will first be asked how
long the tutorial took them to complete, in minutes. They will then be
presented with the option to download a copy of their answers, in either
pdf, html, or rds format, to their Downloads folder. By default, the
name of the downloaded file will be the id
of the tutorial
with _answers
appended, followed by a file suffix
indicating the file type.
So, for example, a tutorial with an id
equal to
getting-started
will generate a file called
getting-started_answers.pdf
if the student selects the pdf
download option.
