[R] seek() - What is the largest integer that can be used?

[Brian Ripley]

This is discussed in the R-admin manual.  You cannot use integers, and 
'where' is documented as numeric, not integer.  You may have to set 
options at configure time, depending on your OS (although recent versions 
of R are good at figuring these out).

On decent 32-bit OSes this does work.  You haven't studied the posting 
guide and hence failed to tell us what yours is, nor have you provided

(Nor have you told us your R version.)

That will not work unless your OS supports seek on files > 2GB, in which 
case direct seek should work.
