explore and document continuous integration and github actions

[njtierney]

Continuous Integration means that you can push something to GitHub and then trigger something magical like:

• Checking if an R package builds
• An rmarkdown report knits
• There are spelling mistakes

I think it would be valuable to discuss how to set up continuous integration, and perhaps produce a short (<5 minute) screencast of establishing continuous integration.

Also, GitHub Actions is this new service that looks like it could maybe replace travis CI and appveyor (cc @jennybc @cboettig @coatless) - it would be neat to explore this as well.

I'd like to explore this. I've only used travis CI, but I want to learn more about this.

Some more awesome examples here:

I particularly like the feature for being able to write \document in a pull request and it runs roxygen on the latest commits.

This would be amazing!

Would you see this as a breakout discussion type thing?
I would be interested

[jimhester]

If you want I could do a short live screencast doing a tour of GitHub Actions for R during the unconf, assuming we can find a time when I or you guys are not sleeping. (I am in U.S. Eastern Standard Time (GMT-5))

ping @jimhester we would love your input, are you around?

[orchid00]

@jimhester can we do 5:30 pm your time? we are starting at 5:00 pm your time so we might need some setting up time. :)

[jimhester]

Sure 5:30 works for me! It looks like you guys are making a great start already
