Re: [Rd] Autocompletion for the new S3 generic @ method?
I agree, this is a good idea and would be very helpful in interactive contexts.
I have a draft patch implementing this feature here:
https://github.com/r-devel/r-svn/pull/122
(Append “.patch” to the URL to get a raw patch.)
Regards,
Tomasz

Re: [Rd] Autocompletion for the new S3 generic @ method?
Hi Tomasz,
I haven't had a chance to look at your patch yet (also I can't accept it as
I'm not on R-core), but patches for consideration should be submitted to
bugzilla (https://bugs.r-project.org), not the unofficial github mirror of
the the SVN repo.
Best,

Re: [Rd] Autocompletion for the new S3 generic @ method?
Thanks, we are discussing the details, but we will definitely add
something along those lines before 4.3.0 is released.
