Step 1. Create a new Plumber API#

RStudio IDE has a sample Plumber API that is available out of the box. For this guide, we are going to utilize the sample Plumber API because everyone has access to it, and it allows us to focus on the task of publishing the Plumber API to RStudio Connect instead of manually creating the Plumber API from scratch. Let's begin!

  • Open the RStudio IDE.
  • From the menu bar, select File > New File > Plumber API.... RStudio IDE New File options screen capture

  • If you are prompted to install additional packages that are required, click Yes.
  • Give your new Plumber API a name and click Create. New Plumber API window

   The script for your Plumber API displays in the editor.

Now, we should confirm that the Plumber API was successfully created.
