# okay, now to figure out a short list of rutter ppa cran packages that travis can install, esp to avoid macos compiling huge number of packages, like xml2, which often fail, and are barely needed.

# testthat deb already depends on: r-cran-cli, r-cran-crayon, r-cran-digest, r-cran-ellipsis, r-cran-evaluate, r-cran-magrittr, r-cran-pkgload, r-cran-praise, r-cran-r6, r-cran-rlang, r-cran-withr

# with removal of dependencies, will have to use:
# _R_CHECK_PACKAGES_USED_IN_TESTS_USE_SUBDIRS_=FALSE for checks on travis
