Hello everyone! 

I have a problem with the balance data in the operator sample. When I have to sample size per class what should I put for class? I have one variable that I have set to 'label' and that is the variable I want to balance the data on. 

The error when I try for example class='label' or the name of the class (in my case 'species') and the size='50' is:
Message: Calculation of covariance matrices not possible for data sets with zero rows.
