If you have more than one version of fixx(), then the one that is used is
the one that comes first in the search path. The search path is revealed
by the search() function. So if you can learn to control the search path,
then you can control which version of fixx() is used. That would be my

Tal and David, thanks for your messages.
I should have added that I tried all variations of true/false values for
the exact and correct parameters. Running with correct=FALSE makes only a
tiny change, resulting in W = 485, p-value = 0.0002481.
At one point, I also thought that the discrepancy bet

You can fairly easily simulate from the exact distribution of W:

It seems your numbers has ties. What happens if you run wilcox.test with
