About multiple target values resampling

[luna57-lr]

Thanks for your research article on regression tasks for " UBL: an R Package for Utility-Based Learning". It helps me a lot!!!

I wonder how to handle with multiple target values resampling. For all examples in your article refer to one target value. So i tried to use your package to resample data with one target each time. But after resampling, the data amount is different when i use different target value.I want to how to solve it!

Looking forward to your reply!
