I am confused about what I believed was artefects from reading .csv files with big numbers.
Finally I checked using the console and this is what I get, the same as when importing:
>
>longnumber<-635024810560380000
>longnumber
[1] 635024810560380032

I have tried setting "options(digits=22) and also 20 and 18 with no difference. R-version is x64 3.0.1

Does someone know or guess why this happens?

Yours
