I am wondering if the
RDataFrame have a similar functionality to
TTree::CopyTree. After searching a bit, I am not sure I find the answer. For
TTree::CopyTree, I can specify the starting entry and number of entries to save. I am not sure
Snapshot provide similar functinality. If they do, please forgive this stupid question and could you please provide me the solution?
Many thanks in advance!
