wilcoxon rank test - problems

Giorgio Pioda
Hi volks,

just cross checking test between R and Gnumeric (I use both
in my lectures)...

The Wilcoxon Rank test gives systematically wrong results since:

1) The S- is not summed up but calculated from the theorical progression and
2) The N value is apparently wrong in presenc on ties (actually to low)

Apparently the S+ sum is correct, so iguess the evil is in the N calculus.

Regards

Giorgio Pioda

P.S: I've 1.12.18 on debian stable and 1.12.31 on debian testing and both
shows the same error.
