Easily exposing the Gmail API from R.

• retrieve data from your email
  • drafts: my_drafts = drafts()
  • history: my_history = history(start_num)
  • labels: my_labels = labels()
  • messages: my_messages = messages("search query")
  • threads: my_threads = threads("search query")
• Create and send emails and drafts: see sending_messages vignette
• manage email labels programmatically: modify_thread(thread_id, add_labels=c("label_1"), remove_labels=c("label_2"))
• put things in the gmail trash
  • messages: trash_message(message_id)
  • threads: trash_thread(thread_id)
• take things out of the gmail trash
  • messages: untrash_message(message_id)
  • threads: untrash_thread(thread_id)
• delete directly without using the trash
  • messages: delete_message(message_id)
  • threads: delete_thread(thread_id)
