[R] mean()=sum()

[Hannu Kahra]

There is a bug (or a feature) in R-0.63.1 such that mean() and sum()
result into identical values in the following example.

> mydata <- read.table("a:\\undata.txt", header=T)
> summary(mydata[2])
        UN       
 Min.   : 3.20  
 1st Qu.: 5.20  
 Median :13.60  
 Mean   :11.94  
 3rd Qu.:18.45  
 Max.   :21.80  
> mean(mydata[2])
[1] 1707.9
> sum(mydata[2])
[1] 1707.9
>

I have used the bdr0631 Windows version.
