One unit test in the R package is currently broken. Steps to reproduce on Mac

export CXX=/usr/local/bin/g++-8 CC=/usr/local/bin/gcc-8
Rscript build_r.R
cd R-package/tests
Rscript testthat.R

This results in the following error at the ends of the logs

[LightGBM] [Info] Saving data to binary file /var/folders/xq/wktq4zdx4jd3qdpk34d28m940000gn/T//RtmpiY1DzV/lgb.Dataset_1555

This class could be used instead of cd file https://catboost.ai/docs/concepts/input-data_column-descfile.html when creating Pool from filez. The class should have init function, methods load and save, and Pool init method should be able to use object of this class instead of cd file during initialization.

Is your feature request related to a problem? Please describe.
When generating generating targeted attacks the method arguments generate(x, y=None) can be confusing. In this case y usually refers to the target label for the attack, but users may accidentally put the correct label there, rendering the attack ineffective.

Describe the solution you'd like
Maybe we should change that

In Python XGBoost one can provide weights for each row of the data, see http://xgboost.readthedocs.io/en/latest/python/python_api.html#xgboost.XGBClassifier.fit. I tried to look for a way to specify such weights in SharpLearning, but could not find it. Is this possible?

We should add BART as one final algorithm after xgboost and before SuperLearner - it's usually the best single model and it would be helpful to explain it to people.

Once #15 is implemented and we have a ::usage message for the integration-step condition function, this information should be included in the Steps display. I imagine for instance a tooltip when the user hovers over the green functions like IGtQ or GtQ

The implementation of this issue will require changed in [ShowStepFormatt

When any of our functions branch based on the user's input we should provide a warning message or note.

Should computation be paused for confirmation? Current plan is that computation should not be paused.
