Dear Guixer,

Can you please add these two r packages in guix? Thanks in advance.
I am not sure how to create this patch, and this is what I did:

guix import cran -a git -r 'https://github.com/timoast/signac/'

(define-public r-signac
  (let ((commit
          "e0512d348adeda4a3f23a2e8f56d1fe09840e03c")
        (revision "1"))
    (package
      (name "r-signac")
      (version (git-version "1.1.1" revision commit))
      (source
        (origin
