set_github_pat(force_new = FALSE, validate = interactive(), verbose = validate)



forget existing pat, always ask for new one.

prints a message showing the credential helper and PAT owner.


Returns TRUE if a valid GITHUB_PAT was set, and FALSE if not.


Packages that require a GITHUB_PAT can call this function to automatically set the GITHUB_PAT when needed. Users may call this function in their .Rprofile script to automatically set GITHUB_PAT for each R session without hardcoding any tokens on disk in plain-text.
