Roofit - fitting ranges

Hi there

I am trying to set the range of a fit in roofit. I have tried

string sel;
sel=“100.<mx&&mx<1000.”;
RooFitResult*fitting = pdf.fitTo(*data, Range(sel.c_str()));

However I get the error message:

Error: Function Range(sel.c_str()) is not defined in current scope

I get this same error if I try to setRange before. I am using root 5.16.8 rooFit V2.07.

Hi,

You have to do

using namespace RooFit ;

first to import the Range() function into your
namespace.
