Hi, Everybody!
I have a big table which named table_x, and all the elements in the table is very large!
Now I want to do the summay on the talbe_x[,3].
Unfornately, I can't get the right result!
And the R give the warning messages as follow:
> sum(table_x[,3])
>[1] NA
>Warning message:
>interger overflow in sum(.);please use sum(as.numeric(.))
