Hi. Just a quick note: CRAN is the group that runs the package
repository. It would be R Core who would decide whether to add those
LAPACK routines that you are asking for. There's a big overlap between
the membership of the two groups, but they are separate.
If you don't get a response from R Core to this message, you could try
posting a similar message to the R-devel mailing list -- it's the one
about changes to R itself. Or you could post it as a feature request on
bugs.r-project.org (but for that you need an account; see
https://www.r-project.org/bugs.html for a discussion of the procedure).

Dear R developpers,
On the 20th of July, I sent an email to the CRAN team asking respectfully if
they would consider adding more LAPACK routines to the R's source tree. Since,
I have not received a response from them, I now assume that maybe I used the
wrong communication channel (and I apologise if this is the case).
My goal is to revive the "IndependenceTests" package, which was archived in
2021.
I was able to resolve most of the issues, but I still have 2 WARNINGs and 1
NOTE, such as:
Warning: GNU Extension: Nonstandard type declaration COMPLEX*16 at (1)
I cannot solve these issues without modifying several (old) Lapack Fortran
source files.
In Section 6.7 of the "Writing R Extensions" manual, I read that the current set of
LAPACK subroutines included in R "might be supplemented".
Moreover, in
https://github.com/SurajGupta/r-source/blob/master/src/modules/lapack/README
I see that some Lapack files (not all the ones I need, unfortunately) were
added over the years to the R source tree.
The file I would like to be added is:
zhpevx.f
which in turn needs those below that are not in the R Lapack:
lsame.f
xerbla.f
zhptrd.f
zlanhp.f
zstein.f
zupgtr.f
zupmtr.f
Would you kindly let me know if:
1.
A formal request to add these LAPACK routines to R's source is something the
CRAN team would consider?
2.
Alternatively, would a submission with these remaining warnings still be
acceptable?
I fully understand if this falls outside the scope of CRAN's intended support,
but any guidance would be greatly appreciated.
Thank you in advance for your time and consideration.
I wish you a nice day.
Kind regards,
Pierre L.
