#####
# R for travis: see documentation at https://docs.travis-ci.com/user/languages/r

# Travis by default runs eg:
# install:
# - R -e 'devtools::install_deps(dep = T)'

# script:
# - R CMD build .
# - R CMD check *tar.gz

# and it looks like it already runs sessionInfo(), see:
# https://github.com/travis-ci/travis-build/blob/master/lib/travis/build/script/r.rb
