True, I made a mistake here. Still, I have problems to visualize my data (not 
the example code I used). I just see a flat line instead a proper plot...

Another example code with creating a strange plot:

x <- rnorm(100) + 100
maxval <- max(x)
boxplot(x, notch=TRUE, xlim = c(0,maxval), horizontal = TRUE)

Any idea?
