Dear R users and developers:
I got this message when I try to make the summary of a numeric variable,
> summary(Dep)
Min. 1st Qu. Median Mean 3rd Qu. Max.
0.000e+00 1.192e+07 2.739e+07 6.538e+07 1.858e+09
Warning message:
Integer overflow in sum(.); use sum(as.numeric(.))
and it fails to make the sum (for calculate the mean), but I don't
understand the "Integer overflow"
If I type the following command,
> summary(as.numeric(Dep))
Min. 1st Qu. Median Mean 3rd Qu. Max.
0.000e+00 1.192e+07 2.739e+07 5.306e+07 6.538e+07 1.858e+09
it works fine.... but I still don't undertand way it doesn't work without
the "as.numeric" coerce, when other functions like "sd()" worked fine.
Thank you very much for your advice
Kenneth Cabrera
P.S.: The length of Dep is 5297
And I am working on W2K in R1.4.1. version.
