It looks like both items 1 and 3 have already been implemented in the
development version of R; see
https://github.com/r-devel/r-svn/blob/main/doc/NEWS.Rd (search for
"notin" or "confint.default")
It looks like your attached patches got stripped from the e-mail. As
https://www.r-project.org/mail.html discusses:
> Furthermore, most binary e-mail attachments are not accepted, i.e.,
they are removed from the posting completely. As an exception, we allow
application/pdf, application/postscript, and image/png (and x-tar and
gzip on R-devel). You can use text/plain as well, or simply paste text
into your message instead.
(I don't know what format your attachments were in, but they didn't
make it.)

Hello R developers,
I would like to contribute three improvements to the R source:
1.
*S4 object support for **confint.default()*
-
confint.default() now works on S4 objects as long as suitable coef()
and vcov() methods exist.
2.
*substring()** and **substr()** improvements*
-
Both functions now accept i2 = NULL, allowing extraction until the
end of the string.
-
Improves convenience and aligns with user expectations.
3.
*Introduction of **%notin%** operator*
-
%notin% added as a base R idiom for !(x %in% table).
-
Enhances readability and avoids repeated negation in user code.
*Motivation:*
-
Enhance S4 object compatibility.
-
Improve string handling convenience.
-
Provide a cleaner syntax for common negation of %in%.
*Impact:*
-
Backward compatible; no breaking changes for existing S3 workflows.
The corresponding patch files are attached to this email.
I hope these changes are helpful. I look forward to any feedback or
suggestions you may have.
Thank you for your time and for maintaining R!
Best regards,
Aakriti Kushwaha
