You can actually switch to 'Trusty' aka 14.04.
That has been around for a bit, and AFAIK works with both the old scheme
(ie
r-travis) or the new scheme. [ I am partial to the old scheme which I now
use
via this fork http://eddelbuettel.github.io/r-travis/ -- and my drat and
digest packages were the first to adopt it. ]
We can take this off-line, but this should work. I first used this when I
needed g++-4.8 and I am pretty sure I have a .travis.yml somewhere using
g++-4.9 because it was needed in one project. "Yes we can."
