devtools::install and install_github do not pass on Additional_repositories on when installing deps?

[cboettig]

If I have package A that depends on package B, which depends on package C; and B & C are in the listed Additional_repositories drat repository, it seems devtools::install() fails to find package C when trying to install B (and thus fails to install A & B). A simple install.packages("A", repo="my.drat.repo") works fine.

For a concrete example:

install.packages("RNeXML", dep=TRUE, repos=c("https://cran.rstudio.com", "http://packages.ropensci.org"))

Works just fine. But

devtools::install_github("ropensci/RNeXML", deps=TRUE)

fails by failing to install the suggested dependency rrdf because rrdflibs is "not available", even though both are on the drat repo.

Also, the discussion in the remotes vignette fails to mention drat use. Given that CRAN supports it, and other packages use it, you may want to mention this (as a non-devtools alternative).

@cboettig I just opened a PR that should address your issue (as long as you specify your repos appropriately)

@eddelbuettel That vignette was written to explain the remotes feature of devtools, not as a general review of available CRAN alternatives. However if you would like drat to be mentioned in it I am sure we would be happy to merge a pull request with the change.

Thanks @jimhester , very nice!

@jimhester could do if you think it fits -- I was mostly coming from the 'well remotes is not the only way to do this' angle of actually mentioning the fact that CRAN now formally supports Additional_repositories. The remotes documentation, focused as it is, seems to imply it was the only game in town.
