... Which is the best of all possible reasons for having it available
in R. And indeed it may be there -- but not under that name.

"Fisher's post-hoc test" may be ambiguous, but one interpretation is
Fisher's Least Significant Difference (LSD) test, and you can find
this as one component of the result returned by ezStats():


Hock is a very nice drink, but whether post-hock you should use LSD
is doubtful ...

As to "Fisher's combination test", I'm not sure whether this is
meant to be something different from the above.
