Hi,
I have a naive question. In RooFit, I have a line like:
ws->factory(“EDIT::mypdf(pdf,X=Y)”);
but I get the error:
ERROR:ObjectHandling – RooAbsCollection: cannot replace “X” with already existing "Y"
which I think is because it refuses to replace if Y already occurs. (I tried to simply the example above.)
Why does this happen, and is there any way around this?
Thanks,
Eric
