[R-pkg-devel] Order of repo access from options("repos")

[Dirk Eddelbuettel]

Greg,

There are AFAICT two issues here: how R unrolls the named vector that is the
'repos' element in the list 'options', and how your computer resolves DNS for
localhost vs 172.17.0.1.  I would try something like

   options(repos = c(CRAN = "http://localhost:3001/proxy",
                     C = "http://localhost:3002",
                     B = "http://localhost:3003/proxy",
                     A = "http://localhost:3004"))

or the equivalent with 172.17.0.1. When I do that here I get errors from
first to last as we expect:

   > options(repos = c(CRAN = "http://localhost:3001/proxy",
                     C = "http://localhost:3002",
                     B = "http://localhost:3003/proxy",
                     A = "http://localhost:3004"))
