A demo of using plumbertableau to create APIs that Tableau can consume.

• Code: https://github.com/SamEdwardes/demo-plumber-penguins
• API Deployment: https://colorado.rstudio.com/rsc/demo-plumber-tableau-penguins/
• Tableau Deployment: https://us-west-2b.online.tableau.com/#/site/rstudio/workbooks/472632?:origin=card_share_link

API Deployment

Git-backed

After making any code changes run the following:

renv::snapshot()
rsconnect::writeManifest("app")

Next, push your changes to git. RStudio Connect will then automatically redeploy the app.

Programatic

You can also deploy the app using the rsconnect api:

rsconnect::deployAPI(
  api = "app",
  appFiles = c("plumber.R"),
  appTitle = "Plumber Tableau Penguins"
)

Tableau Deployment

After deploying the API follow the instructions from https://rstudio.github.io/plumbertableau/articles/tableau-developer-guide.html to deploy in Tableau. For example, you must consider Tableau to use Connect as an Analytics Extension:

Calling the API from Tableau

Create a field named Selected Dimension Value that will allow users to change which field they want to identify outliers based on.

Create a field named Is Outlier? which calls the plumber API using the SCRIPT_BOOL function. For each row in the data this will return TRUE or FALSE. Values that are TRUE are outliers.

Construct the scatter plot that colors each data point based on its outlier status.
