I included this because it can be difficult to tell if your RStudio Addins are up to date. I may add new features that you want but you won't hear about the updates. This function checks if an update is available, using GitHub tags. If an update is available, a modal dialog is shown when you start the regexplain gadget. This only happens once per R session, though, so feel free to ignore the message.
check_version(gh_user = "gadenbuie", gh_repo = "regexplain",
this_version = packageVersion("regexplain"))
GitHub user account
GitHub repo name
The currently installed version of the package
