Swirl & Permissions

• Swirl creates and stores files and folders on a user's computer when installing new courses or to save a user's progress in a lesson.
  • Courses are installed in the directory that results from system.file("Courses", package = "swirl")
  • User progress and logs are saved in the directory that results from system.file("user_data", package = "swirl")
• If the user does not have write permissions, they can change the location of where swirl accesses this data.
  • To set course installation location use: swirl_options(swirl_courses_dir = file.path("some", "other", "directory"))
  • To set where user progress and logs are saved use: swirl_options(swirl_data_dir = file.path("some", "other", "directory"))
• These options need to be set during every R session, therefore they should be added to the user's .Rprofile. You can find out more about R start-up and the .Rprofile file here.
