Description
First reported on the forum:
struct c_t{
|
double a;
|
double b;
|
};
|
|
void p1_read()
|
{
|
struct c_t c;
|
c.a = 1;
|
c.b = 2;
|
TFile * f1 = new TFile("f1.root","RECREATE");
|
TTree * t1 = new TTree("t1", "t1");
|
t1->Branch("c",&c);
|
t1->Fill();
|
t1->Fill();
|
|
t1->Write();
|
f1->Close();
|
|
ROOT::RDataFrame aData("t1", "f1.root");
|
aData.Display("a")->Print();
|
}

fails to recognize "a" or "c.a" as a valid column name.
