Great. I checked that you are a member of Debian Med packaging team and
thus you should have commit permissions to SVN where most of our R
packages reside (some of them are in Git as your example r-bioc-limma.)
So I would advise to commit your current state of work to the repository
of your choice even in a not finished state - just mark this by using
"UNRELEASED" as target distribution and perhaps add a TODO entry inside
the changelog.

I'm not really sure whether there is a 1:1 relation. What I personally
do when building R packages is the following: Use
pbuilder
to be pretty sure that all Build-Depends are fullfilled. Once you
have all Build-Depends set this is usually the set of Depends you need
as well.

I'm not very competent in R itself but if the build process asks for
those packages, just add them. This can not be wrong.
Kind regards and thanks for considering building such packages in Debian
Med team
Andreas.
