Hi! I had not answered yet because I thought I would be too verbose.
If so, please do a Laura -v instead of Laura -vvvvvvv.
Thanks for writing :) it encourages me a lot.

Yes! I love reading ALL the documentation, but I focused mainly in
chapters 3 to 5, and the part about the certificate stuff is 6. That
is why I did not know about it.

Yes! I knew that the package was already available for guix, but I
just wanted to see the template, with guix import, to use it for
others.

I have already answered this :( I know I don't have time to do things
this way, at least for the contribution(s)

Something I faced after writing, was that in the link one of you provided:
[1]https://guix.mdc-berlin.de/
I have all the packages that are already available in guix. I like
using the guix package command to practice that too, but i found it
practical to see packages easier. I found out that package aspi
(https://CRAN.R-project.org/package=aspi) is not available, and I
would like to ask you if you believe it is a good candidate.
One available package, according to [1] is r-abe
(https://cran.r-project.org/web/packages/abe/index.html)
I wanted to see the template, so I ran:
$ guix import cran abe
And got the template, that matches even the version, and everything
stated in the site.
But then I tried:
$ guix package -i r-abe and got no results.
In fact, after running the command you have just provided, r-abe is
not appearing in the r.txt file.
I can't understand why that is happening. Am I missing something, or
is there maybe an inconsistency between [1] and the guix installed in
my foreign distro?
Just wanted to install it to run guix edit to check if the suggested
packages were already available or if I needed to package them too,
but I have installed r-ade4, which has both imports and suggests, and
I have just run:
$guix import cran ade4
And noticed that it only states in the template the Import package (MASS)

Here is my template for aspi (I named it for myself r-aspi.scm). I ran
guix download from its site, and also guix hash to convert it to
base32:

(define-public r-aspi
(package
  (name "r-aspi")
  (version "0.2.0")
  (source
    (origin
      (method url-fetch)
      (uri (cran-uri "aspi" version))
      (sha256
        (base32
          "a7izhueiqsdjs2eo7dfyb63cqje7mbqz6ennlyoynxxucbhpdnta"))))
  (build-system r-build-system)
   (home-page
    "https://cran.r-project.org/web/packages/aspi/";)
  (synopsis
    "Analysis of Symmetry of Parasitic Infections")
  (description
    "Tools for the analysis and visualization of bilateral asymmetry
in parasitic infections.")
  (license gpl3+)))
And that's were I ended up today (it is still Tuesday, almost 10pm)

Thanks :) I knew about the regex, but everything  is always welcome :)
sometimes it is true that after reading too much info you end up
messed up if you do not have enough time to practice and try
everything.
