Georg,

A boxplot does not have a mean-bar. It has a median bar.

Subject: [R] boxplots

Dear R user group,

   I am working with boxplots and cannot solve the following problem:

> data<-c(0,15,0,60,0,0,0,0,0,60,60,0,60,0,30,0)
> data
 [1] 0 15 0 60 0 0 0 0 0 60 60 0 60 0 30 0
> boxplot(data)

The boxplot has the first hinge and the mean-bar both at 0... Why is this
the mean is clearly >0!
Thanking you and wishing you an excellent day, Georg.
