install_version fails because of CRANextra

[oseiskar]

devtools::install_version apparently tries to download already installed packages from the "CRANextra" repo, which can cause the installation to fail for no good reason.

My getOption('repos') is

                            CRAN                            CRANextra 
     "https://cran.rstudio.com/" "http://www.stats.ox.ac.uk/pub/RWin" 

and when I try devtools::install_version('data.table', '1.9.4'), the very end of the
installation fails with

...
** testing if installed package can be loaded
*** arch - i386
*** arch - x64
* DONE (data.table)
Downloading package from url: http://www.stats.ox.ac.uk/pub/RWin/src/contrib/Archive/data.table/data.table_1.9.4.tar.gz
Error in download(bundle, x$url, x$config) : 
  client error: (404) Not Found

even though the package was installed succesfully (library(data.table) succeeds).

If I remove "CRANextra" from repos, with, e.g.,

devtools::install_version('data.table', '1.9.4', repos='https://cran.rstudio.com/')

the installation succeeds.

same kind of problem here. install_version() fails when length(repos) > 1.
My current work-around is to set the repos params, e.g. repos = getOption("repos")[1]

@jimhester could you take a look at this one too please?

[jimhester]

@hadley might be easier for me (and you) to keep track of if you just assign these issues to me. It doesn't look like I can assign them to myself. 😦
