You missed the part where we create packages ("R CMD build") out of source
repos, and then place those packages in package repos.  That is what drat is
for.

maybe you missed the part where the OP tried to use
https://github.com/waddella/loon in 'Additional_repositories'? AFAIK you can't 
use a simple git source code repository of a package.

i'm maintaining various alternative repos myself ( https://reaktanz.de/R/ ; 
https://files.kde.org/rkward/R/ ; https://undocumeantit.github.io/repos/l10n/ 
) using roxyPackage instead of drat.

And with Additional_repositories, it plays with the install.packages() and
update.packages() functions just as it should -- because package dependency
resolution is a powerful mechanism we like to use whereever possible.

do you mean that a dependency is automatically fetched and installed from an 
*alternative* repo configured via 'Additional_repositories'? i didn't get that 
to work. i only ever managed CRAN to see that the package is there during 
checks, but not install it.

take the 'sylly' package:
  https://cran.r-project.org/package=sylly

it has

  Additional_repositories: https://undocumeantit.github.io/repos/l10n

in its DESCRIPTION and suggests 'sylly.de', 'sylly.en', and 'sylly.es'. but 
when i run

  install.packages("sylly", dependencies=TRUE)

i get:

  Warning: dependencies ?testthat?, ?sylly.de?, ?sylly.en?, ?sylly.es? are not
    available

am i missing something?
