Subject: Re: [R-sig-Epi] Converting dates from the Persian calendar to Gregorian
Hi Bendix,
Thanks - had not heard of Emacs before although just looking at it briefly it
seems to be more of a text editor than a database type program, also although
it converts from gregorian to other calendars, I'm not sure if it converts in
the opposite direction.
I'll post this to R-devel and see if there are any takers.
Best wishes,
Amy

Yes it might be a good idea to pose this to the R-devel list as a
facility that should be included in R --- presumably with the same facilities
as in emacs.
Best regards,
