if (interactive()) {
  # setup disk.frame to use multiple workers these may use more than two
  # cores, and is therefore not allowed on CRAN. Hence it's set to run only in
  # interactive session
  setup_disk.frame()
  
  # use a Shiny GUI to adjust settings
  # only run in interactive()
  setup_disk.frame(gui = TRUE)
}

# set the number workers to 2
setup_disk.frame(2)

# if you do not wish to use multiple workers you can set it to sequential
setup_disk.frame(future_backend=future::sequential)
