Yes it does

I set for Wilcoxon Test
* first is greater
* conf.int=T
a<-rnorm(100), b<-rnorm(100)


see image in appendix

## Vorbereiten
## Berechne
rk.temp.x <- substitute (a)
rk.temp.y <- substitute (b)
rk.temp <- wilcox.test (eval (rk.temp.x), eval (rk.temp.y), alternative = 
c("greater"), mu = 0.00000000, paired = FALSE, exact = TRUE, correct = TRUE, 
conf.int = TRUE )
## Drucke Ergebnisse

## Aufräumen
rm (list=grep ("^rk.temp", ls (), value=TRUE))
