The Epiverse-TRACE is an open source project, and we welcome contributions of all kinds: new documentation, fixes to existing material, bug reports, and reviews of proposed changes are all welcome.
By contributing, you agree that we may redistribute your work under our license. In exchange, we will address your issues and/or assess your change proposal as promptly as we can, and help you become a member of our community. Everyone involved in Epiverse-TRACE agrees to abide by our code of conduct.
The easiest way to get started is to file an issue to tell us about a spelling mistake, some awkward wording, or a factual error. This is a good way to introduce yourself and to meet some of our community members.

If you do not have a GitHub account, you can send us comments by email. However, we will be able to respond more quickly if you use one of the other methods described below.
-
If you have a GitHub account, or are willing to create one, but do not know how to use Git, you can report problems or suggest improvements by creating an issue. This allows us to assign the item to someone and to respond to it in a threaded discussion.
-
If you are comfortable with Git, and would like to add or change material, you can submit a pull request (PR). Instructions for doing this are included below. For inspiration about changes that need to be made, check out the list of open issues.
Note: if you want to build the website locally, please refer to The Workbench documentation.
- If you wish to change this tutorial, add issues and pull requests here.
- If you wish to change the template used for workshop websites, please refer to The Workbench documentation.
There are many ways to contribute, from writing new exercises and improving existing ones to updating or filling in the documentation and submitting bug reports about things that do not work, are not clear, or are missing. If you are looking for ideas, please see the list of issues for this repository.
Comments on issues and reviews of pull requests are just as welcome: we are smarter together than we are on our own. Reviews from novices and newcomers are particularly valuable: it's easy for people who have been using these tutorials for a while to forget how impenetrable some of this material can be, so fresh eyes are always welcome.
Our tutorials already contain more material than we can cover in a typical workshop, so we are usually not looking for more concepts or tools to add to them. As a rule, if you want to introduce a new idea, you must (a) estimate how long it will take to teach and (b) explain what you would take out to make room for it. The first encourages contributors to be honest about requirements; the second, to think hard about priorities.
We are also not looking for exercises or other material that only run on one platform. Our workshops typically contain a mixture of Windows, macOS, and Linux users; in order to be usable, our tutorials must run equally well on all three.
For a tutorial your role could be of a Developer, Reviewer, or Maintainer. Our goal is to keep an homogeneous package environment among Developers and Reviewers of a “feature branch” different to main. This implies that:
- We will use
sandpaper::use_package_cache()
in the R project. - The Developer will need to register the package version to use in a
renv.lock
file. - The Reviewer will need to restore environment defined by Developer, if needs to build the website locally.
You can follow these steps:
- Update the set of workbench packages:
install.packages(c("sandpaper", "varnish", "pegboard", "tinkr"),
repos = c("https://carpentries.r-universe.dev/", getOption("repos")))
To contribute with a new episode:
- Create a new feature branch. Write in there your contribution.
- Create an Issue to report the start of your WIP feature branch. Add the WIP label to it. This aims to keep one contributor per feature branch.
- Create a new episode with
sandpaper::create_episode_md("Episode Name")
If you need to work with the most recent versions of packages:
- Use
sandpaper::update_cache()
. This will:- Fetch updates from CRAN or GitHub,
- Update the
renv.lock
file with package specific versions, and - Update the cache. This is located in a folder called
renv/library/
in the same directory of therenv.lock
, only visible locally.
- Push the updated
renv.lock
file to the GitHub “development branch”.
If you need to work with a specific stable version of a package:
- Use
sandpaper::pin_version()
. This will:- Update the
renv.lock
file with the specific version, - Update the cache.
- Update the
- Push the updated
renv.lock
file.
If you need the version of a package that is not programmatically loaded, i.e., is loaded as part of the dependency tree of an specific package:
- Create an
episodes/install.R
file that lists the installation scripts for the packages in your lesson. - Run the
episodes/install.R
file to install the list of packages. - Run
sandpaper::update_cache()
. Before you accept the update, verify that the expected version number is listed as an update. After this, review therenv.lock
file if this modified the file as expected.
To merge your new episodes:
- Make a Pull request (PR). You can follow the stesp on using GitHub.
You can follow these steps:
- Install the set of workbench packages:
install.packages(c("sandpaper", "varnish", "pegboard", "tinkr"),
repos = c("https://carpentries.r-universe.dev/", getOption("repos")))
- Clone the repository or Pull to update the branch to review on Rstudio.
- Checkout or Switch to the branch to review.
- Use
sandpaper::manage_deps()
to align the packages in your cache with the ones in therenv.lock
file (defined by the Developer).- You may need to manually install certain packages used in the lesson - please check the output in case
sandpaper::manage_deps()
fails. This can be resolved on a trial and error basis.
- You may need to manually install certain packages used in the lesson - please check the output in case
- Render lesson with
sandpaper::build_lesson()
. This will open an HTML tab in your browser to review. This HTML format is how the website is going to look like online. - Make any edit suggestion to the
.Rmd
files inside theepisodes/
folder of the branch under review. For big changes, create an issue first.
If you have issues at the Render step, follow these two steps:
- Verify or wait until the branch is under Pull Request (PR) with all checks passed.
- Access to the
md-outputs-PR-##
branch on GitHub to read the.md
files for each episode.
Consider that:
- The number
##
is equal to the PR number. .md
files contain generated lesson content for review with knitted text, code, and figures.- These
.md
files generate the.html
of the website and look similar to how it's going to look like online.
- Make any edit suggestions in the PR online on GitHub.
You can follow this reference:
- Update steps above from any discussion on issues.
- Review how to maintain a Healthy Infrastructure.
- Review how to Automate a Pull Request.
- Review topics on Collaborative Lesson Development
To write a new episode, follow these guidelines
- Add new
.Rmd
files to theepisode/
folder. - Add file name to the
config.yaml
underepisodes:
in the order you want the tutorials to appear in. - Add required data sets to the
episodes/data/
folder. - Add glossary terms to
learners/reference.md
. - Add commonly used links to
links.md
. - Add a visible callout for prerequisites at the beginning following the ETK modules notation.
- Add an introduction section with the expected summative assessment.
- Add diagrams using Diagrammer with greek letters for parameters to visually represent mathematical models.
- Use callouts for complementary concepts and function arguments details.
- Review how callouts need to be coded in plain text.
- Review when to use the spoiler snipped.
- Request a review via PR.
If you choose to contribute via GitHub, you may want to look at How to Contribute to an Open Source Project on GitHub. In brief, we use GitHub flow to manage changes:
- Create a new branch in your desktop copy of this repository for each significant change.
- Commit the change in that branch.
- Push that branch to your fork of this repository on GitHub.
- Submit a pull request from that branch to the upstream repository.
- If you receive feedback, make changes on your desktop and push to your branch on GitHub: the pull request will update automatically.
NB: The published copy of the lesson is usually in the main
branch.
Each lesson has a team of maintainers who review issues and pull requests or encourage others to do so. The maintainers are community volunteers, and have final say over what gets merged into the lesson.
- If you need to get the latest commits in the
main
branch to use them in your development, we recommend rebasing your feature branch. Rebase will keep the commit history linear. First, make sure that you are the only contributor in thefeature
branch, then:- In the local repository, follow all these five steps:
- Switch to the
main
branch:git checkout main
- Pull the
main
branch:git pull
- Switch to your
feature
branch:git checkout feature
- Rebase your
feature
branch ontomain
branch:git rebase main
- Push your rebased
featured
branch using the--force
option (this must be a forced update):git push --force
- Switch to the
- In the remote repository, only if you are in a PR:
- Update your PR branch with Update with Rebase.
- To pull changes to your local repository from an updated PR branch with rebase in the remote, run:
git pull --rebase
- In the local repository, follow all these five steps:
