Hello, I am new in Root, I imported a RooDataSet from some data(mass), and I took the Sweights.
I have RooDataSet::data[mass,Nums_sw,L_Nums,Numb_sw,L_Numb] and I want to add a new “column” to the RooDataSet with values between 0 , 1 to enumerate the events (entries). I tried, but I couldn’t do that.
