[R] confidence interval for wilcox_test

[RomanGelzhaeuser]

Hello,
When using wilcox_test from coin I got a sample estimator which does not lie
in the confidence interval.(see below) How is that possible? (The
documentation said that both referre to some kind of pseudo median but it
seems to be the same for both the confidence interval and the samplle
estimator)
