okay, so (afaik) this is just a github repos which contains an exact
copy of the github version of the problematic package (here: loon). I
would then (at some future point) just do a pull to get the latest
source, create the package from there and essential refer to it from
Additional_repositories via: "Additional_repositories:

(so if CRAN would actually archive packages directly to a github
repos, one would not need to create a separate copy/repos'es... :-) ).

Btw, at the bottom of http://eddelbuettel.github.io/drat/DratFAQ.html
you refer to 'wikipediatrend' as an example for how to use
Additional_repositories. The link points to
which does not contain such a line. Might be better to just refer to
your R paper.
