-# Options used for building or testing your R package can be
-# controlled by uncommenting one or both of the following; the values
-# here are the defaults:
-env:
-  global:
-    - R_BUILD_ARGS="--no-build-vignettes --no-manual"
-    - R_CHECK_ARGS="--no-build-vignettes --no-manual --as-cran"
-    - RunAllRcppTests="yes"
 
-# See the travis docs for more information:
-#   http://about.travis-ci.org/docs/user/build-configuration/#The-Build-Matrix
-
-
-# Also works but is slower as it needs devtools:
-# - ./travis-tool.sh install_deps
-
-# Currently unused (and GSL used for illustration)
-#  - ./travis-tool.sh aptget_install libgsl0-dev
