Hi PetitFort,

I presume you want to install the RWeka package. We will firstly need to investigate whether this package can be installed on the platform, in particular from a security standpoint. If this is the case, we’ll install it for you in order to make sure dependencies are correctly setup.

In the meantime, please check in the right bottom panel of AlphienStudio in the “Packages” tab what packages are currently available to users; for machine learning, you can use caret, e1071, xgboost, randomforest and many more. Let us know if you need help getting started with them.

Thanks
