Upps, sorry, those results where totally non-sense. I'm to tired ;-)
here are the results of my current implementation for the dataset above
(but data were correct!):
> wilcox.exact(treat, contr)
Wilcoxon rank sum test
data: treat and contr
W = 35, p-value = 0.0989
alternative hypothesis: true mu is not equal to 0
> wilcox.exact(treat, contr, alternative="l")
Wilcoxon rank sum test
data: treat and contr
W = 35, p-value = 0.9648
alternative hypothesis: true mu is less than 0
> wilcox.exact(treat, contr, alternative="g")
Wilcoxon rank sum test
data: treat and contr
W = 35, p-value = 0.05568
alternative hypothesis: true mu is greater than 0
Sorry again,
Torsten
