Reproducible example

To reproduce these warnings:

1. Build the R package from source

sh build-cran-package.sh
R CMD INSTALL lightgbm_*.tar.gz

2. Run the unit tests.

cd R-package/tests/
Rscript testthat.R

It's hard to tell from the logs which specific tests each of these warnings come from. I recommend running the tests one at a time, interactively.

Notes for Contributors

You do not have to address all of these warnings in one pull request. Pull requests that only fix one or some of them are welcome!
