Examples

if (interactive()) {
  # Option 1: Use the pre-made sample file from the package
  # Get the path to the sample data file
  sample_file <- system.file("extdata", "sample_data.rds", package = "quallmer.app")

  # Launch the app and upload this file through the UI
  qlm_app()

  # Option 2: Load the data and save your own copy
