Subject: [R] mean()=sum()
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.
