takeAction method

Implementation

void takeAction(method) {
  // Run the R scripts.  For different selected cleanup, the text will be
  // different as well as the script to execute.

  // For check special conditions:

  // Delete Ignored but no variables Ignored.

          To delete the Ignored variables you will first need to choose some
          variables to Ignore from the **Dataset** tab **Role** page.

  // All good.
