I’m trying to use the S option to retrieve the correlation coefficient from a linear fit, but the TFitResult thing seems not to be working.
I’m using Python, with ROOT 5.25, here’s the relevant part of the code:
from ROOT import TH1I, TCanvas, TGraph, TGraphErrors, TF1
intensity_graph = TGraphErrors(file_name)
line = TF1("line", "pol1")
result = intensity_graph.Fit("line","S")
AttributeError: 'int' object has no attribute 'Print'
it seems that the pointer to the fit result is being converted to an int, despite the “s” option
