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
