Dear all, Onetime 0.1.0, a utility package of interest to package developers, is now on CRAN:
https://cran.r-project.org/package=onetime Onetime uses lockfiles to perform an action only once (ever, or with an expiry date) on a given computer. For example, it can send a message or warning: for (i in 1:10) { onetime_message("This will be shown only once", id = "my-message") } It also lets you send a message and confirm the user doesn't need to see it again: onetime_message_confirm("User can opt not to show this message again", id = "my-confirm-message") Onetime checks that you have permission to store files on the user's computer, and allows package authors to ask for this permission using check_ok_to_store(). Package authors can use onetime to print one-off informative messages for new users, or to do other one-off actions. Documentation is available at https://hughjonesd.github.io/onetime/.
