I would like to initialize a TTreeFormula after it’s declared. I tried (v. 6.12/06):
TTreeFormula f; //stuff f.SetName("f"); f.SetTitle("2*x"); f.SetTree(tree);
But I think my change is being ignored: only the parameters passed at declaration
TTreeFormula f("f", "...", tree) matter.
TTreeFormula::Init is protected, I suppose I need a similar command to make this work. Which one?
