[R-pkg-devel] issues with SOfun - package upload

Good evening,

I am trying to upload my package, called PdPDB 2.0.
When building and checking the package with R-studio with --as-cran
option
selected, everything looks ok but, once I tried to upload the package
to
CRAN I had the following reply:

*"Strong dependencies not in mainstream repositories:*
*??SOfun*
** checking package namespace information ... OK*
** checking package dependencies ... ERROR*
*Package required but not available: 'SOfun'"*

I understand the issue it with SOfun that is a package I downloaded
and
installed from this github url: https://github.com/mrdwab/SOfun

I came back to CARN policies and I have read:


*"Packages on which a CRAN package depends should be available from a
mainstream repository: if any mentioned in ?Suggests? or ?Enhances?
fields
are not from such a repository, where to obtain them at a repository
should
be specified in an ?Additional_repositories? field of the DESCRIPTION
file
(as a comma-separated list of repository URLs) or for other means of
access, described in the ?Description? field."*

So, I updated the DESCRIPTION file as follows:
Additional_repositories: http://news.mrdwab.com/install_github.R

Before to proceed to submission, I would like to know if this is the
right
way to proceed or I misinterpreted the submission procedure.

Thank you for reading this email,
Best,
