Dear ROOT developers,
I am trying to open multiple files with the same TTree using RDataFrame in pyROOT. I am trying something along
from ROOT import RDataFrame frame = RDataFrame("TTreeName", ["filename1", "filename2", "filename3"])
but that does not seem to work. Is it possible to open multiple ROOT files in one RDataFrame in pyROOT somehow? If yes, are the TTrees from the ROOT files merged by RDataFrame?
ROOT Version: 6.14.04
