this seems to speed up the travis builds by about 50%.
i believe the big improvement is from cacheing the packages
the suggestion from the following blog post is to use remotes instead of the
r_packages
entry we currently have in the travis.yml file, but I haven't tried that.https://blog.rstudio.com/2016/03/09/r-on-travis-ci/
