Dear R developpers,
Two months ago, I sent an email to the CRAN team asking if they would consider
adding more LAPACK routines to the R's source tree. I have not received a
response from them, which led me to assume that maybe I used the wrong
communication channel. (I apologise if this is the case.)
My goal is to revive my "IndependenceTests" package. It was archived in 2021
(because I had not been able to solve various issues on time).
I have now been able to resolve most of the issues, though I still WARNINGs
such as:
Warning: GNU Extension: Nonstandard type declaration COMPLEX*16 at (1)
It is my firm belief that I cannot solve these issues without modifying several
(old) Lapack Fortran source files.
Now, 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". Also,
in the
https://github.com/SurajGupta/r-source/blob/master/src/modules/lapack/README
file,
I see that some Lapack files were added over the years to the R source tree.
But not all the ones I need, unfortunately.
The file I would like to be added to the R source tree is the following:
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 the R's source tree is
something that can be considered?
2.
Alternatively, would a submission with these few remaining warnings still be
acceptable?
I fully understand if this falls outside the scope of R Core Team or CRAN's
intended support, but any guidance would be greatly appreciated.
Thank you in advance for your time and consideration.
Kind regards,
