In the roofit manual and on the class reference on the root webpage there are mentions of the
ShowConstant
argument that paramOn member function takes. However, this argument should be
ShowConstants
with an “s” at the end. As I said this error is found in the most recent RooFit manual I could find with Google (as it’s not easy to find on the RooFit homepage), 2.91-33, and the error is found on the class reference:
root.cern.ch/root/html/RooAbsPdf … df:paramOn
Thanks,
