How to create an R package 📦

Check out the slidedeck to quickly build your first package! 🌴 ☀️ 🌊

Here's an alternate Git/RStudio workflow you can use to get your package started:

1. Create an new GitHub repo on https://github.com/new
2. Create a new Git R project (File --> New Project --> Version Control --> Git --> [paste in Repository URL] & [Create Project])
3. Use devtools::create(".") to initiate a package. You can say "no" when it asks you to overwrite the RProj file.

And some keyboard short-cuts:

• Cmd + i = auto-indent

• Cmd + shift + t = devtools::test()
• Cmd + shift + d = devtools::document()

If you are on Windows, Use Ctrl in the place of Cmd for the above shortcuts work.
