Your first webR-powered Quarto Document using the {quarto-webr} Extension and RStudio

[@WashingtonSSilva-jt3lt]

Fantastic! Thank you very much and congratulations! It will be a disruptive resource in my classes, I'm from Brazil and webR + Quarto will be a fundamental resource to deal with the numerous limitations we face in our laboratories and with the equally serious limitations of students in obtaining computers suitable for training in data science

Thanks for letting us know! Feel free to reach out about any issues as they arise.

@@thecoatlessprofessor7674 I have some questions that I believe are quite basic, is github issues the best way to ask these questions? Thanks!

[@matthewson8917]

This would be a great addition to my teaching materials, thank you. What versions of R/RStudio/Quarto are required for quoarto-webr?

[@thecoatlessprofessor7674]

Great to hear! Regarding requirements, please note: The authoring environment must have: - Quarto v1.4.545 or above (this is required for use with the `revealjs` format) - R v4.3.0 or above - RStudio 2023.12.0+369 or VS Code 1.85 with the Quarto Extension As of this writing, the current version of {webR} is v0.2.2 and provides R 4.3.0. Though, this is not the latest version of R 4.3.2 (Eye Holes). I'm expecting the version of {webR} to be bumped to v4.3.2 in the near-term v0.2.3 release.

Can this output be integrated into an existing html webpage? e.g. into a uni lgms? Is there somewhere this process is outlined?

[@thecoatlessprofessor7674]

If the LMS supports adding an HTML page, you can create one using the `html-document` example. This file can then be uploaded onto the LMS and linked to students. github.com/coatless/quarto-webr/tree/main/examples/html-document If you have more questions, please feel free to open an issue on the project's tracker: github.com/coatless/quarto-webr/issues/new/choose

@@thecoatlessprofessor7674 thanks for the quick reply. Due to security, the LMS people will need to change the COOP/COEP clearances before it'll work, is that correct?

[@thecoatlessprofessor7674]

@@drtuki it should just work out of the box. Going with COOP/COEP headers will allow SharedArrayBuffer to work, which gives you a bit more features and a faster execution. But, the default PostMessage approach should be perfect! (Please don't use the ServiceWorker option!)

Thank you very much for this quick guide video! I tried it on my quarto blog and but it keeps showing "Loading webR" when rendered. Any ways to rectify this issue? Thanks!

[@thecoatlessprofessor7674]

Thanks for the kind words! Though, I'm sorry to hear about the "Loading webR" issue. Have you had a moment to try the steps outlined in: quarto-webr.thecoatlessprofessor.com/qwebr-troubleshooting.html#stuck-at-loading-webr I'll try to add a new video or improve the deployment method for websites in the next release (0.3.8)
