Re: [Rd] Autocompletion for the new S3 generic @ method?
This should be enabled now in R-devel and R 4.3.0 by writing
.AtNames() methods.
findMatches() is also exported now; this is basically grep(), but will
do fuzzy matching if it's activated.

Thanks, we are discussing the details, but we will definitely add
something along those lines before 4.3.0 is released.

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,
~G

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.)

[Rd] Autocompletion for the new S3 generic @ method?
Hello,
In the current R-devel @ is S3 generic, so we can do things like - for example
- use it to extract matrix rows by name:
.S3method("@", "mm", function(object, name) object[name,])
m <- structure(matrix(rnorm(20), ncol=2), dimnames=list(paste0("row",
1:10), paste("col", 1:2)), class="mm")
m@row1
However, seems like currently it does not support autocompletion.
Wouldn’t it make sense to add a method like .EtaNames() which would provide tab
autocompletions for x@ in the same way current .DollarNames() does for
x$?
Regards,
Karolis K.
