Dear all,

I want to read a 1.2 G file with 136,736,218 numbers with scan function, and
then want make a histogram with those numbers, but it showed Error: cannot
allocate vector of size 2.0 Gb. How can I import the file then?

The version I used:
> sessionInfo()
R version 2.8.1 (2008-12-22) 
i686-pc-linux-gnu
> mem.limits()
nsize vsize 
   NA    NA
and the computer I use has 4G memory in total.

Thank you very much!
