gradethis helps scale feedback for [learnr] exercises. Instructors can use a model solution as a template or write highly customized testing logic to provide specific feedback for common mistakes.

gradethis is designed for use in [learnr] tutorials. We recommend that you first be comfortable writing learnr tutorials before you begin incorporating exercise feedback with gradethis. You can learn more about learnr tutorials with the [learnr package documentation][learnr].



## Installation

gradethis is still in development and not on [CRAN](https://CRAN.R-project.org) yet.

The development version of gradethis can be installed from GitHub with:

```r

# install.packages("remotes")

remotes::install_github("rstudio/gradethis")

```

## Usage

To use gradethis in a learnr tutorial, start by loading gradethis after learnr in the `setup` chunk of your tutorial:

````markdown

```{r setup}

library(learnr)

library(gradethis)

```

````

gradethis provides two grading modalities. You can:

1. Compare student code to model solution code with `grade_this_code()`, or

1. Write custom grading logic with `grade_this()`.

Learn more about where and how to write exercise-checking code in `vignette("gradethis")`.

There are two main places to get help:

1. The [gradethis tag on RStudio Community](https://community.rstudio.com/tag/gradethis) is a friendly place to ask any questions about gradethis and the R Markdown family of packages. Additionally, we invite instructors to join the [Teaching Category on RStudio Community](https://community.rstudio.com/c/teaching/13), where any discussions about teaching are welcome.

1. [Stack Overflow](https://stackoverflow.com/questions/tagged/gradethis) can be a source of answers to common gradethis questions. It is also a great place to get help, once you have created a [reproducible example](https://reprex.tidyverse.org) that illustrates your problem.
